  [PowerPC] Add target feature requirement to builtins

Clang has mechanism to specify required target features of a built-in
function. This patch adds such definitions to Altivec, VSX, HTM,
PairedVec and MMA builtins.

This will help frontend to detect incompatible target features of
bulitin when using target attribute syntax.
