a2bf4efce2 * use indirect imports for FPC_EMPTYCHAR if necessary 
* make not of FPC_EMPTYCHAR as external assembler symbol

017d4edbbb * fixed memory typecast of complex procdef to simple procvar: left.resultdef 
is a procdef, but after the load was finished it's actually already a
    (complex) procvar. And since it's a memory location, the result of the
    typecast is a pointer to the typeconvnode's resultdef (fixes
    tests/tbs/tb0594.pp and others for llvm)

0fc1fd6ac1 * replaced current_procinfo.currtrue/falselabel with storing the true/false 
labels of LOC_JUMP in the node's location. This generates some extra jumps
    for short circuit boolean and/or-expressions if optimizations are off, but
    with optimisations enabled the generated code is the same (except for JVM
    because the jump threading optimisation isn't enabled there yet).

187c2af20e * tcgtypeconvnode.second_proc_to_procvar converted to the high level code 
generator, so it can now handle i8086 near and far pointers generically
- removed almost all of t8086typeconvnode.second_proc_procvar, since it's no
  longer needed. Only a few assertions are left there to ensure that we don't
  accidentally attempt to take the address of a near procedure in a far code
  memory model, because the calling conventions are incompatible.

07b2982e77 Don't do ARM FoldShiftLdrStr peephole optimization if there's an offset in the reference. 
Use UXTH+UXTB instructions instead of two shifts on processors that supports that.

76f6de5cf1 Refactor tobjectdef.find_implemented_interface out into unit defcmp so that the recently introduced cycle between symdef and defcmp can be broken again. 
defcmp.pas:

  * change method call of "find_implemented_interface" into function call
symdef.pas:
  - tobjectdef: remove method "find_implemented_interface"
  - remove use of unit "defcmp"
pgenutil.pas:
  * change method call of "find_implemented_interface" into function call
  + add use of unit "defcmp"
ncgcnv.pas, ncnv.pas, pdecobj.pas, pdecsub.pas, pdecvar.pas:

f3a1c749fb * tcgtypeconvnode.second_int_to_int: reuse 8 and 16-bit-sized register locations on targets with 32-bit-only registers when casting to larger size (except ShortInt to Word cast). This is possible because upper bits of such registers are always kept valid by code generators (see 'maybeadjustresult' method in cgcpu.pas). Removes a lot of useless register moves.
