[PATCH] Allow vectorization of few missed llvm intrinsic calls in BBVectorizor

[Karthik Bhat]

Hi hfinkel,

Hi Hal,
I'm currently going through and trying to understand BB Vectorizer while doing so i found that few llvm intrinsic function calls which can be vectorized are missed in the switch case of isVectorizableIntrinsic as a result these intrinsic functions are not getting vectorized. This patch modifies isVectorizableIntrinsic function and covers these intrinsic functions in the switch case so that they get vectorized.
Does this patch look good to commit?
Thanks
Karthik Bhat
