Changes since v4:
* Patch 1, "tcg/ppc: Introduce Altivec registers", is divided into
ten smaller patches.
* The net result (code-wise) is not changed between former patch 1
and ten new patches.
* Remaining (2-7) patches from v4 are applied verbatim.
* This means that code-wise v5 and v4 do not differ.
* v5 is devised to help debugging, and to better organize the code.
Changes since v3:
* Add support for bitsel, with the vsx xxsel insn.
* Rely on the new relocation overflow handling, so
we don't require 3 insns for a vector load.
Changes since v2:
* Several generic tcg patches to improve dup vs dupi vs dupm.
In particular, if a global temp (like guest r10) is not in
a host register, we should duplicate from memory instead of
loading to an integer register, spilling to stack, loading
to a vector register, and then duplicating.
* I have more confidence that 32-bit ppc host should work
this time around. No testing on that front yet, but I've
unified some code sequences with 64-bit ppc host.
* Base altivec now supports V128 only. Moved V64 support to
Power7 (v2.06), which has 64-bit load/store.
* Dropped support for 64-bit vector multiply using Power8.
The expansion was too large compared to using integer regs.
