represent complex locations (required for full x86-64 ABI support,
which is not yet implemented) -> lots of special result handling
code has been removed and replaced by the parameter handling
routines
+ added support for composite parameters (and hence function
results) to tcg.a_load_ref_cgpara() (so it can be used for
handling, e.g., 64 bit parameters on 32 bit platforms)
* the above fixed writing past the end of allocated memory when
handling records returned in registers on x86-64 whose size is
not a multiple of 8 bytes (mantis #16357)
- removed the x86-64 and PPC specific versions of a_load_ref_cgpara(),
as they are now handled correctly by the generic version
* moved the responsibility of allocating tcgpara cpu registers
(using paramanager.allocparaloc()) from the callers of
cg.a_load*_cgpara() to the cg.a_load*_cgpara() methods
themselves (so the register allocation can be done efficiently
when dealing with function results)
* for the above, renamed paramanager.alloc/freeparaloc() to
paramanager.alloc/freecgpara(), and use paramanager.allocparaloc()
to allocate individual pcgparalocations instead
* fixed the register size of SSE2 function result registers for
x86-64 (when used for floating point), which results in removing
a few superfluous "movs? %xmm0,%xmm0" instructions
* fixed compilation of paramanagers of avr, m68k and mips after r13695
and also updated them for these new changes
