[Mesa-dev] PowerPC: Add Altivec vector add/sub intrisics

This patch add correct vector addition and subtraction 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,
