Add back in the support for 64-bit PPC MacOSX hosts that was
broken in the recent merge of the 32-bit and 64-bit TCG backends.

Richard Henderson d4cba13bdf tcg/ppc: Fix failure in tcg_out_mem_long
With rt != r0 on loads, we use rt for scratch.  If we need an index
register different from base, we can't use rt, but r0 is usable.

Peter Maydell 4196dca63b tcg: mark tcg_out* and tcg_patch* with attribute 'unused'
The tcg_out* and tcg_patch* functions are utility routines that may or
may not be used by a particular backend; mark them with the 'unused'
attribute to suppress spurious warnings if they aren't used.

Richard Henderson a84ac4cbbb tcg-ppc: Use the return address as a base pointer
This can significantly reduce code size for generation of (some)
64-bit constants.  With the side effect that we know for a fact
that exit_tb can use the register to good effect.

As a "utility", it only supported ppc, and in a way that other
tcg backends provided directly in tcg-target.h.  Removing this
disparity is easier now that the two ppc backends are merged.

The new ELFv2 ABI, used by default on powerpc64le-linux hosts,
introduced some changes that are incompatible with code currently
generated by the ppc64 TGC target.  In particular, we no longer
use function descriptors.

This patch adds support for the ELFv2 ABI in the ppc64 TGC
function call and function prologue sequences.
