gallivm: Altivec vector add/sub intrisics
This patch add correct vector addition and substraction intrisics when
using Altivec with PPC. Current code uses default path and LLVM backend
ends up issuing carry-out arithmetic instruction while it is expected
saturated ones.
It also includes a fix for PowerPC where char are unsigned by default,
resulting in bogus values for vector shifting.
