b0458b55a3 Loosen the restriction regarding operator overloads by applying a (modified) patch from JC Chu. This fixes Mantis #22359.
The changes are built up in a way that all operators on two given types are not allowed if a default implementation for that operator exists. This implies that there is a possibility to have a overload work for (in this order) type A and B, but not for B and A. This is for example the case for Set + Enum (which seems to have a default implementation) where Enum + Set is allowed. The added tests try to detect as many default implementations as feasible, but can't cover everything...

aee5380ae0 * merged trunk up to r20882
o support for the new codepage-aware ansistrings in the jvm branch
   o empty ansistrings are now always represented by a nil pointer rather than
     by an empty string, because an empty string also has a code page which
     can confuse code (although this will make ansistrings harder to use
     in Java code)
   o more string helpers code shared between the general and jvm rtl
   o support for indexbyte/word in the jvm rtl (warning: first parameter
     is an open array rather than an untyped parameter there, so
     indexchar(pcharvar^,10,0) will be equivalent to
     indexchar[pcharvar^],10,0) there, which is different from what is
     intended; changing it to an untyped parameter wouldn't help though)
   o default() support is not yet complete
   o calling fpcres is currently broken due to limitations in
     sysutils.executeprocess() regarding handling unix quoting and
     the compiler using the same command lines for scripts and directly
     calling external programs
   o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
     to the make command line

c6ca9e5091 compiler:
- add helper function getansistringcodepage which returns explicitly set codepage or 0 in other case
  - add helper function getansistringdef which return a def with explicitly set codepage or cansistringtype in other case
  - change tstoreddef.createnai constructor to allow set codepage in constructor
  - don't convert string constants to rawbytestring. if string constant already has a codepage - preserve it or convert to ansistring codepage (delphi compatible)
  - don't perform string conversion from ansistring to strings with explicitly set codepage (by directive or by compiler switch) and vice versa (delphi compatible)
  + test which covers most of the cases

88df6573a0 * moved de2regtyp() from defutil to hlcgobj, so it can be overridden
(and override for the JVM, making the register type for records
     R_ADDRESSREGISTER instead of R_INTREGISTER there)

8439e1472e * moved def2regtyp() from jvm/hlcgcpu to defutil, and extended it to
handle vectorfpu (floatdef->MMREG) and softfloat (floatdef->INTREG)
  + thlcg.getregisterfordef(), which uses def2regtyp() to allocate a register
    appropriate to hold values of that tdef type
  + generic thlcg.location_force_reg() implementation. Note that for
    low-level code generator targets it may be slightly less efficient than
    the implementation in hlcg2ll (from ncgutil) because it does not play
    any tricks with the register or location size, or with reference offsets,
    to truncate values

    a new object type with this property is added

b4ac714201 * defutil.pas: added UnicodeString to automatable types, fixes compilation of webtbs/tw2649.pp after r16360. However it requires RTL support similar to one for AnsiString to be complete.
* ncal.pas, translate_disp_call(): fixed parameter alignment once more, this time it should be correct for both 32 and 64 bit platforms.

ba700ad2ff * Improvements to Dispatch call handling:
o All signed and unsigned ordinal types are made automatable.
  o Non-automatable types are rejected when parsing dispinterface declarations.
  o Simplified translate_disp_call() a bit.
  o translate_disp_call() now supports non-automatable parameters which can be typecasted to automatable ones. UnicodeString is not yet there, though.
  o Partially fixes #17904: parameters of Variant Dispatch calls are passed by reference when they can be mapped to a variable.

14b95b3b9b * always force range checking for the upper and lower bounds of for-loops if
they are constants (instead of only on 32 bit systems), and always use the

    bounds of longint (mantis #17646)

57bd6d2685 + merged nestedprocvars branch
+ support for nested procedural variables:
    o activate using {$modeswitch nestedprocvars} (compatible with all
      regular syntax modes, enabled by default for MacPas mode)
    o activating this mode switch changes the way the frame pointer is
      passed to nested routines into the same way that Delphi uses (always
      passed via the stack, and if necessary removed from the stack by
      the caller) -- Todo: possibly also allow using this parameter
      passing convention without enabling nested procvars, maybe even
      by default in Delphi mode, see mantis #9432
    o both global and nested routines can be passed to/assigned to a
      nested procvar (and called via them). Note that converting global
      *procvars* to nested procvars is intentionally not supported, so
      that this functionality can also be implemented via compile-time
      generated trampolines if necessary (e.g. for LLVM or CIL backends
      as long as they don't support the aforementioned parameter passing
      convention)
    o a nested procvar can both be declared using a Mac/ISO Pascal style
      "inline" type declaration as a parameter type, or as a stand-alone
      type (in the latter case, add "is nested" at the end in analogy to
      "of object" for method pointers -- note that using variables of
      such a type is dangerous, because if you call them once the enclosing
      stack frame no longer exists on the stack, the results are
      undefined; this is however allowed for Metaware Pascal compatibility)

f5c52b25cd * removed "and not is_class()" condition from is_managed_type(), because
tobjectdef.needs_inittable returns false for classes nowadays (and already
    since quite some time)
  * nevertheless replaced all usages in the compiler of x.needs_inittable with
    is_managed_type(x) (in case some other condition is added again in the
    future) and removed all remaining accompanying "and not is_class(x)"
    checks

40705a085f * renamed is_refcounted_type() into is_managed_type(), because it also
returns true for variants and those aren't refcounted
  * also allow tempnodes for pointers to managed types to be put in
    registers (not sure why it was disabled, and there are no
    testsuite regressions by enabling it)

0cfc6e1cac + support for "univ" in macpas mode: a parameter modifier that allows
passing any value to that parameter which has the same size as the
    parameter (it basically acts as if there is an explicit type conversion
    to the parameter type around the value at the caller side). If a procvar
    has an univ parameter, all procvars whose corresponding parameter
    has the same size as that univ parameter are similarly compatible.

    This transparent compatibility can however cause crashes in case of
    of the procvars when one of the types is passed on the stack and the
    other isn't (because then the called routine will a) load the parameter
    from a wrong location and b) pop the wrong amount off of the stack at
    then end). Therefore FPC will warn in most cases where this can happen.

025ec34e4d + "CExtended" type that is the same as "extended", but conforming to the

5a2ccfff52 --WARNING: start build process with FPC 2.2.4; won't work when
starting with a previous 2.3.1 or compiler built from the objc branch
  + added basic objcprotocol support (only for external protocols
    currently)
     o use in type declaration: "type xp = objcprotocol ... end;"
     o when defining a root class that implements it:
       "type yc = objcclass(xp) ... end" (note: no support yet
       for something like "objcclass(id,xp)" or so)
     o when defining a non-root class that implements a protocol:
       "type zc = objcclass(nsobject,xp) ... end"
     o includes support for "required" and "optional" sections
     o no support yet for the objcprotocol(<protocol>) expression
       that enables getting a class instance representing the
       protocol (e.g., for use with "conformsToProtocol:")
     o message names have to specified in protocol declarations,
       but if an objcclass implements a protocol, the message names do
       not have to be repeated (but if they are, they have to match;
       the same goes when overriding inherited methods)
  + allow specifying the external name of Objective-C classes and
    protocols, since classes and protocols can have the same name
    (and you cannot use the same Pascal identifier in such caseq)
  + added NSObject protocol, and make the NSObject class use it
  + added missing NSObject class methods that have the same name
    as instance methods (added "class" name prefix to avoid clashes)
  * fixed several cases where the compiler did not treat Objective-C
    classes/protocols the same as Object Pascal classes/interfaces
    (a.o., forward declarations, alignment, regvars, several type
     conversions, ...)
  * allow "override" directive in objcclass declarations, and print
    a hint if it's forgotten in an external declaration (because it
    doesn't really matter there, and may make automated header
    conversion harder than necessary) and an error if will be used in
    a non-external declaration (because it is not possible to start
    a new vmt entry-tree in Objective-C, you can only override parent
    methods)
  * reject objcclasses/protocols as parameters to typeof()
  * don't try to test VMT validity of objcclasses/protocols

f36e5411af * split cpu64bit compiler define into
a) cpu64bitaddr, which means that we are generating a compiler which
       will generate code for targets with a 64 bit address space/abi
    b) cpu64bitalu, which means that we are generating a compiler which
       will generate code for a cpu with support for 64 bit integer
       operations (possibly running in a 32 bit address space, depending
       on the cpu64bitaddr define)
   All cpus which had cpu64bit set now have both the above defines set,
   and none of the 32 bit cpus have cpu64bitalu set (and none will
   compile with it currently)
  + pint and puint types, similar to aint/aword (not pword because that
    that conflicts with pword=^word)
  * several changes from aint/aword to pint/pword
  * some changes of tcgsize2size[OS_INT] to sizeof(pint)

8349cde7db * changed byte/word/longbool to be Delphi-compatible (+ similar changes
for qwordbool) + test:
    o assigning true to such a variable now sets them to $ff/$ffff/$ffffffff
    o these types are now all signed
    o converting an integer type to a byte/word/long/qwordbool using an
      explicit type cast keeps the integer's original value stored in the
      bool, instead of forcing it to ord(true)/ord(false)
    (mantis #10233 and #10613, implemented for all architectures, testsuite
     tested for ppc32, sparc and x86)
  * fixed some places where the rtl depended on longbool(true) having the
    value 1
  * extended several boolean tests (and adapted some to no longer assume
    that byte/word/long/qwordbool(true)=1)
  + support for converting to qwordbool in second_int_to_bool for x86, ppc
    and sparc

0040eecf9f + support for extra packing of sets whose lower element number
is <> 0 (Delphi compatible now, + various tests)
  + support for enums and sets in is_in_limit()
  * fixed converting smallset expressions to varsets
  * improved choosing an appropriate common set type when mixing
    set types in an expression
  - removed no longer used normalset code from nadd.pas
  - disabled large set (>256 elements) support for now, because
    they are not yet supported entirely throughout the compiler
    and this causes errors at run time in several situations
