ba1297b1ab + provide also 8 and 16 bit div/mod helper 
* tmoddivnode.first_moddivint does not force a 32 bit helper, the used helper depends now on the resultdef type set by tmoddivnode.pass_typecheck

3f736f6114 * handle the loading of VMT entries at the node level, so it's done in a 
type-safe way (for LLVM, and also internal consistency checking between
    the VMT as generated in nobj.pas and ncgvmt.pas)
   o also converted the VMT validity checking to the node level

d2b8275b99 + support for arbitrary encodings in readstr/writestr 
o set the code page of the temporary "text" file to utf-8 for writestr with
     unicodestring/widestring as destination, so that no data loss can occur
     (+ properly deal with cases whereby part of an utf-8 character is
      written to the textbuf in this case)
   o explicitly pass the code page of the destination ansistring for writestr
     with ansistring as destination and set it for the temporary "text" file
   o set the code page of the text file for readstr

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.

b99cf8d680 * RTL: Changed 'shift' parameter of 64-bit shift helpers to CPU-native size, it doesn't have to be 64-bit because only its lower 6 bits are used. Not using 64 bit parameter improves code quality a bit.

3c3ad705f1 * changed fpc_(u)char_to_shortstr() from a procedure into a function, like 
the other fpc_(u)char_to_*str() routines (exception dates back to the
    time calls to these routines were still inserted "manually" in the
    compiler). Fixes the compilation of "shortstr:=widecharconstant" after
    r23613 and simplifies other code calling this helper + test

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)
