547fa426c7 Fix emit_ansistr_const: its input is not guaranteed to be #0-terminated
Also cleaned up all memory leaks where pchars were allocated, but never freed.
Before the change to dynamic arrays, these pchars were kept in the tai_string,
but now they got copied. Changed the tai_string constructor to support adding
a terminating #0, so we don't need to create intermediates just for that.

a25ebbba3e + added volatility information to all memory references
o separate information for reading and writing, because e.g. in a
     try-block, only the writes to local variables and parameters are
     volatile (they have to be committed immediately in case the next
     instruction causes an exception)
   o for now, only references to absolute memory addresses are marked
     as volatile
   o the volatily information is (should be) properly maintained throughout
     all code generators for all archictures with this patch
   o no optimizers or other compiler infrastructure uses the volatility
     information yet
   o this functionality is not (yet) exposed at the language level, it
     is only for internal code generator use right now

9727f289b1 + tcalo_apply_constalign option to specify that the alignment should be

5e1bb8e408 + tcalo_make_dead_strippable to indicate that a typed constant data block
should be dead-strippable; may imply the creation of a separate section
    (on platforms that dead-strip data based on sections), but does not
    require it
  * replaced all existing tcalo_new_section uses with
    tcalo_make_dead_strippable, as that is their meaning/purpose

b0ff41406a * grouped all tai_real* types into a single tai_realconst type,
to free up space for more ait_* types in taitype (can't have
    more than 32 because they have to fit in a small set)

     byte in the external assemblers

bc0c94c204 fpcdefs.inc: Set fpc_compiler_has_fixup_jmps for powerpcXX and mips CPUs.
psub.pas: Use new fpc_compiler_has_fixup_jmps conditional.
 mips/aasmcpu.pas: MIPS specific fixup_jmps function,
   The insttruction distance calculation is not exact as
   some pseudo-instruction can be expanded to a variable number of real instructions
   real calculation would only be possible if we first 
   convert pseudo-instuctions to real instructions before calling fixup_jmps.

 ncgutil.pas: Revert commit r21791
 ncgcon.pas: Revert commit r21786
 mips/cgcpu.pas: Partial revert of commit r21798, no need to always use A_J,
 as fixup_jmps now handles out of range branches.

8282d6e37a * do not create a global symbol in the middle of ansi/unicodestring
constants on Darwin, because its linker uses global symbols as delimiters
    of subsections for dead code stripping. This was previously solved by
    never making any ansistring constants smart linkable, which is now
    solved

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
