[PATCH] D33236: [PowerPC] Implement vec_xxsldwi builtin.

[Tony Jiang via Phabricator via llvm-commits]

jtony created this revision.

Note this patch is based on the infrastructure in patch https://reviews.llvm.org/D33053 . The vec_xxsldwi builtin is also missing from altivec.h. This has been requested by developers working on libvpx for VP9 support for Google.  This patch implements the vec_xxsldwi builtin by using the existing shuffleVector instruction just in the FE. The implementation here is similar to vec_xxpermdi in the patch https://reviews.llvm.org/D33053.
