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

* Abort if attempting to emit a call without pi_do_call flag set, because the outgoing parameter area determines layout of temps and therefore cannot be created/changed during pass 2.
* Bypass g_concatcopy_move if procedure is a leaf one, due to the restriction mentioned above.
git-svn-id: trunk@23644 -
* Replaced assignment "has_errors:=true" by calling a new procedure SetHasErrors. It simplifies debugging - just set a breakpoint inside SetHasErrors and see the stack back trace to find out where the error has occurred.

assemble.pas, TExternalAssembler.WriteSourceLine:
* don't generate an internal error if no module is found; if the system unit is compiled with -al there can be cases when fileinfo contains only zeros (though I wonder where this comes from; I'll need to investigate this when I have time)
git-svn-id: trunk@23631 -
assemble.pas, TExternalAssembler.WriteSourceLine:
* also respect a module change which can happen if the generated assembler code belongs to a specialized generic
git-svn-id: trunk@23628 -
* Parameters passed in registers are no longer forced to stack, therefore assembler routines using 'lw' instruction to load such parameters must have it changed to 'move' (tb0072.pp).
