- Removed TMIPSProcInfo.needs_frame_pointer, it duplicates pi_needs_stackframe flag.
- Don't save RA for leaf procedures.
* GP is caller-saved register, it does not need saving/restoring as nonvolatile registers. Handle its restore position as a "normal" temp, whose offset is known before secondpass. This allows to handle PIC calls without involving GAS macro processing.

FPHash was duplicated 4 times for different input types. I've
consolidated it to a single function with 3 proxy-functions which can be
inlined.
I've also modified the hash function itself slightly, it now resembled
the original DJB hash and seems to perform a tiny bit better.

using less than 8 bits per element the same as regular char arrays as far
as automatic type conversions are concerned (they have to be explicitly
packed/unpacked) (mantis #24013)

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.
