Sanjay Patel 5e0ce9d13a [X86, AVX] instcombine vperm2 intrinsics with zero inputs into shuffles

This is the IR optimizer follow-on patch for D8563: the x86 backend patch
that converts this kind of shuffle back into a vperm2.

This is also a continuation of the transform that started in D8486. 
In that patch, Andrea suggested that we could convert vperm2 intrinsics that
use zero masks into a single shuffle. 

This is an implementation of that suggestion.
