86feb1c860 tcg: Disambiguate qemu_ld32u with 32-bit and 64-bit outputs.
Some targets (e.g. Alpha and MIPS64) need to keep 32-bit operands
sign-extended in 64-bit registers (regardless of the "real" sign
of the operand).  For that, we need to be able to distinguish
between a 32-bit load with a 32-bit result and a 32-bit load with
a given extension to a 64-bit result.  This distinction already
exists for the ld* loads, but not the qemu_ld* loads.

Reserve qemu_ld32u for 64-bit outputs and introduce qemu_ld32 for
32-bit outputs.  Adjust all code generators to match.

Avoids nasty warnings about flush_icache_range from gcc4 and inability
to compile [cpu-]exec.c with gcc3 and -O, also the function is much
too large to be candidate for inlining anyway.

a35e86c55f Shuffle contents of tcg_target_reg_alloc_order
Move reserved/volatile registers down. Currently qemu_ld/stXX are
marked with TCG_OPF_CALL_CLOBBER and since memory accesses are
frequent and R3 through R12 are volatile moving this down results in
less spills and tighter generated code.
