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.

rs6000 RFC2609 vector blend, permute instructions
