tcg-ppc: Avoid code for nop move

While these are rare from code that's been through the optimizer,
it's not uncommon within the tcg backend.

tcg-ppc: Cleanup tcg_out_qemu_ld/st_slow_path

Coding style fixes. Use TCGReg enumeration values instead of raw
numbers. Don't needlessly pull the whole TCGLabelQemuLdst struct
into local variables. Less conditional compilation.

No functional changes....

tcg-ppc: Use conditional branch and link to slow path

Saves one insn per slow path. Note that we can no longer use
a tail call into the store helper.

tcg-ppc: use new return-argument ld/st helpers

These use a 32-bit load-of-immediate to save a mflr+addi+mtlr sequence.
Tested with a Windows 98 guest (pretty much the most recent thing I
could run on my PPC machine) and kvm-unit-tests's sieve.flat. The
speed up for sieve.flat is as high as 10% for qemu-system-i386, 25%...

tcg-ppc: fix qemu_ld/qemu_st for AIX ABI

For the AIX ABI, the function pointer and small area pointer need
to be loaded in the trampoline. The trampoline instead is called
with a normal BL instruction.

tcg/mips: inline bswap16/bswap32 ops

Use an inline version for the bswap16 and bswap32 ops to avoid
testing for MIPS32R2 instructions availability, as these ops are
only available in that case.

tcg/mips: only enable ext8s/ext16s ops on MIPS32R2

On MIPS ext8s and ext16s ops are implemented with a dedicated
instruction only on MIPS32R2, otherwise the same kind of implementation
than at TCG level (shift left followed by shift right) is used.

Change that by only implementing the ext8s and ext16s ops on MIPS32R2 so...
