aac74f4d0a * Patch from Inoussa Ouedraogo to make assigning widechar to variant Delphi 2009+ compatible (Bug ID 25719)

f42c1b3720 * Return dynamic arrays in parameter, this was the only managed type still returned in register. Returning managed types in registers requires catching and re-raising exceptions at callee side in order to finalize result and avoid memory leaks. While such behavior makes little difference with generic setjmp-based exception handling, it becomes very inefficient as SEH-styled exception handling is being introduced. 
The new behavior is also Delphi-compatible.

cf20bbc886 * RTL, Pos() with Variant: added 'const' modifiers to avoid unnecessary local copies of managed parameters.

7a0ae38700 + also specify the parameter def when allocating a parameter via 
getintparaloc + adapted all call sites of getintparaloc. This
    led to a number of additional, related changes:
   o corrected the type information for some getintparaloc parameters
   o don't allocate some intparalocs in cases they aren't used
   o changed "const tvardata" parameter into "constref tvardata" for
     fpc_variant_copy_overwrite to make pass-by-reference semantics
     explicit
   o moved a number of routines that now have to call find_system_type()
     from cgobj to hlcgobj so that cgobj doesn't have to start depending
     on the symtable unit
   o added versions of the cpureg alloc/dealloc methods to hlcgobj that
     call through to their cgobj counter parts, so we can call save/restore
     the cpu registers before/after calling system helpers from hlcgobj
     (not implemented in hlcgobj itself, because all basic register
      allocator functionality is still part of cgobj/cgcpu)

49700e675c * Changed code generation for variant assignments to typecast arguments to TVarData instead of using pointers. Fixes one (probably the ugliest one) case of non-disposed temp variables: 
When arguments are temps, they are supposed to be released by tcgcallnode.release_para_temps. However, taking address with taddrnode effectively changes original location of temp to some LOC_REGISTER, tcgcallnode.release_para_temps no longer sees the original location and therefore does not free such temps.
