* omit several error messages when in_generic is true because the error can be checked only during specialisation, resolves the issue reported in #21592

example: %OPT=-gl win32%-WN
if % is found in OPT list, the string after % is only added
to the compiler options if current target is
contained in the list of the string before the % sign.
+ Add %DELOPT dotest option.
can be used in two variants
%DELOPT=-Crio
will suppress -Criot from TEST_OPT if it appears exactly
(-Criot will not match).
%DELOPT=-C* will suppress all options starting with -C.

in code and not in constants. In the case of primitive types constant nodes
are used while complex types like arrays, records and objects use a local
variable which is initialized to zero once at the entry of the method (the
variable is reused if Default() is used for the same type multiple times in
the same method). For this a new compilerproc was added which uses FillChar
to initialize the given memory area to zero.
This fixes Mantis #9420.
+ psystem.pas: Added Default symbol to system unit
+ htypechk.pas: Added function "is_valid_for_default" which checks recursively
whether the given type can be used with Default at all.
Forbidden types are files, helpers, ObjC and C++ types. This
check is used for records, arrays and objects only if the mode
is a non-Delphi one, as Delphi ignores these types on lower
levels.
+ msg/errore.msg: Added error message for unsupported types for Default()
+ symconst.pas: Added a new enum value vo_is_default_var which is used for the
local variables utilized by Default() so their initalization
and finalization can be avoided.
+ pexpr.pas: Add handling of Default() intrinsic to "statement_syssym"
+ ninl.pas: Extended tinlinenode by a method which returns the correct node for
a Default() and used that method in handle_typecheck.
* ncgutil.pas: Check for new flag "vo_is_default_var" when initializing and
finalizing local variables.
* ppu.pas: increase PPU version
+ psub.pas:
* Added a new routine which zeros defaultvars of a symtable.
* Use this routine inside "initializevars".
* Also use this routine to initialize the staticsymtable of the unit/program.
* Adjusted ppudump, because of the new enum value.
+ Added implementation of fpc_zeromem to system unit.
+ Added tests for Default()

* Fix for InterLockedCompareExchange on ARMEL
InterLockedCompareExchange would not return the current data on failure.
Getting this to work correctly is a bit tricky. As kuser_cmpxchg does
not return the set value, we have to load it.
There is a tiny chance that we get rescheduled between calling
kuser_cmpxchg and loading the value. If the value changed in between
there is the possibility that we would return the Comperand without
having done an actual swap. Which might cause havoc and destruction.
So, if the exchange failed, compare the value and loop again in case
of CurrentValue == Comperand.
* Improve testing of InterLockedCompareExchange
Added a test to check for the case when Comperand is different from the
current value.

if expr1 has sideeffects. This can't be done safely even in case of
short boolean evaluation, because expr1 may return the inverse the
second time its called (and "0 or 1" is not the same as "0", and
neither is "1 and 0"), based on comment by Michael Karcher
* perform a full string compare when comparing stringconstnodes
before the string constant labels have been generated (patch by
Michael Karcher, mantis #21255)

name of a formal and of a real definition don't match

- for AnsiChar prefer ShortString, AnsiString, UnicodeString, WideString, ... (LongString?)
- for WideChar prefer UnicodeString, WideString, AnsiString, ShortString, ... (LongString?)
- remove old code from htypechk which made AnsiChar const = AnsiString,ShortString and WideChar const = WideString,UnicodeString - it is no longer needed since defcmp performs the required comparisons

* defcmp.pas:
+ Extend compare_def_ext by the possiblity to specify whether strict or
loose comparison of undefined defs should be applied.
* in strict mode undefined defs are incompatible to all other defs
except other undefined defs
* in loose mode undefined defs are equal to anything (this is how
FPC behaved up to now)
+ Enable the strict mode in compare_paras so that overloads with
generic type parameters are possible
* ptype.pas, single_type:
If the generic dummy of the currently parsed generic is encountered in
non-Delphi modes then we need to return the current genericdef. This
condition needs to be checked using the ObjName of the def, because
the link from the type symbol to the current def is not yet
established
+ added test for bug report
