* Moved fixup_jmps to target-specific classes for powerpc,powerpc64 and MIPS, cleaned out remaining $ifdef's. A slight functionality change is that fixup_jmps is now called before adding the procedure end symbol, not after, but that should not matter.

* MIPS: handle get_frame internally, so it sets pi_needs_stackframe flag on current procedure. This makes possible not to force pi_needs_stackframe on every procedure and thus omit saving/restoring $fp register when it is not necessary.

* MIPS: set pi_do_call flag for assembler procedures with stackframes, so in PIC mode it further receives pi_needs_got in PIC mode and allocates the GP save temp.
...
* Deallocate GP save temp in epilogue to avoid warnings when compiled with -dEXTDEBUG
* g_concatcopy: don't check alignment, this allows single byte or word locations to be copied with 2 instructions. Larger unaligned references are supposed to be handled in g_concatcopy_unaligned instead.

+ MIPS: implemented parameter location reusing, eliminating second copy of (potentially large) records passed by value. When parameter is passed both in registers and stack, let it have a single LOC_REFERENCE location on callee side, and store relevant registers on stack (into 16-byte area reserved by ABI) early in prologue.

* MIPS: pi_needs_got is necessary when doing unsigned to float conversions (it uses a global constant) and also if procedure does any calls in PIC mode.

MIPS procinfo improvements:
...
- 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.

* MIPS: allocate 16-byte outgoing parameter area also for procedures declared as 'assembler' without 'nostackframe'. This is a half-measure because there is no way to determine correct size to allocate for such procedures (probably we must add some directive to specify it). The same generally applies to all targets with fixed stack, not just MIPS.

* MIPS: fixed layout of stack frame in case procedure does only low-level calls (via a_call_name, etc.). A 16-byte outgoing parameter area must be allocated regardless of actual parameter count.
...
* 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.
