tcg-ppc64: More use of TAI and SAI helper macros

Finish conversion of all memory operations.

tcg-ppc64: Use TCG_REG_Rn constants

Instead of bare N, for clarity. The only (intentional) exception made
is for insns that encode R|0, i.e. when R0 encoded into the insn is
interpreted as zero not the contents of the register.

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: Fix and cleanup tcg_out_tlb_check

The fix is that sparc has so many mmu modes that the last one overflowed
the 16-bit signed offset we assumed would fit. Handle this, and check
the new assumption at compile time.

Load the tlb addend earlier for the fast path....

tcg-ppc64: Reformat tcg-target.c

Whitespace and brace changes only.

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.
