rs6000 Add vector blend, permute builtin support
GCC maintainers:
The following patch adds support for the vec_blendv and vec_permx
builtins.
The patch has been compiled and tested on
powerpc64le-unknown-linux-gnu (Power 8 LE)
powerpc64le-unknown-linux-gnu (Power 9 LE)
with no regression errors.
The test cases were compiled on a Power 9 system and then tested on
Mambo.
