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.
