GCC maintainers:
The following patch adds support for the vector shift double builtins
for RFC2609.
The patch has been compiled and tested on
powerpc64le-unknown-linux-gnu (Power 9 LE)
and Mambo with no regression errors.
Please let me know if this patch is acceptable for the mainline
branch. Thanks.
