tcg: Name the opcode enumeration.

Give the enumeration formed from tcg-opc.h a name: TCGOpcode.
Use that enumeration type instead of "int" whereever appropriate.

On ppc32 make tb_set_jmp_target1 behave like it does on a ppc64

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.

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....
