rtl/objpas/classes/classes.inc, TThread.GetCurrentThread:
* instead of checking CurrentThreadVar and reading it again afterwards we read it first into Result and check this value; this way we have one read access in the normal case and one read and one write access in the worst case

differentiate between 64 bit and 128 bit (R_SUBMMWHOLE) SSE vector regs,
and support spilling/assembling for R_SUBQ SSE registers (8 bytes)
(mantis #23962)
We currently never use the full 128 bit of an SSE register, and
spilling for those hasn't been implemented yet either (R_SUBMMWHOLE
SSE regs are spilled into a 4-byte temp currently -> can overwrite data)

+ Favor 'weak' parameter in a_call_name of both thlcgmips and TCGMIPS.
* make_simple_ref and a_loadaddr_ref_reg: require input references to be 'raw' (no refaddr=addr_pic, etc) and do not use GP as base/index. If it's not true, raise an internal error. When addr_pic_call16 or so needs to be generated, it must be done without calling the mentioned methods.
* thlcgmips.a_call_name: generate PIC sequence for procedures declared as 'external', instead of 'cdecl', this is more correct because ABI has only one calling convention.
- make_simple_ref_fpu removed, there's no reason to handle references to floating-point data in different way.
- a_loadaddr_ref_cgpara override also removed, generic method does the job just well.
- thlcgmips.a_call_ref and a_call_reg overrides removed because indirect calls are now always done using $t9.

symconst.pas:
+ add "sto_has_operator" to "tsymtableoption"
pdecsub.pas:
+ include the flag "sto_has_operator" for all operator declarations and their owning symtables
htypechk.pas, tcallcandidates:
* create_candidate_list: only check for operator overloads if the record does indeed declare some
* collect_overloads_in_units: only check for operator overloads if the unit does indeed declare some
utils/ppudump.pp:
+ respect the new "sto_has_operator" flag

* Build unixcp for all unix-like systems.
* Use the unixcp unit in cwstring instead of winiconv.inc.
- Deleted winiconv.inc
- Reverted r22410,r22411,r22428. The compiler will use the unixcp unit to get a default code page for ansistrings.

In trunk TBookmark is of type array of bytes (TBytes), prior this it was Pointer (to memory block of BookmarkSize where is stored "bookmark data").
BufDatset uses GotoBookmark and passes address of bookmark, which is okay when TBookmark was pointer, but when it is dynamic array then on entry into method FPC_DYNARRAY_INCR_REF is called, where is accessed "array header" in unallocated memory, which leads to invalid pointer operation.
Making parameter as const will avoid invoking reference counting mechanism. Bug #23381. Discussed also in DB-Core ML.
