Sanjay Patel be9ee96926 [X86, AVX] instcombine common cases of vperm2* intrinsics into shuffles 
vperm2* intrinsics are just shuffles. 
In a few special cases, they're not even shuffles.

Optimizing intrinsics in InstCombine is better than
handling this in the front-end for at least two reasons:

1. Optimizing custom-written SSE intrinsic code at -O0 makes vector coders
   really angry (and so I have regrets about some patches from last week).

2. Doing mask conversion logic in header files is hard to write and 
   subsequently read.

There are a couple of TODOs in this patch to complete this optimization.
