Sanjay Patel c18792fc71 [InstCombine] canonicalize vector select with constant vector condition to shuffle 
As discussed on llvm-dev ( http://lists.llvm.org/pipermail/llvm-dev/2016-August/104210.html ): 
turn a vector select with constant condition operand into a shuffle as a canonicalization step.
Shuffles may be easier to reason about in conjunction with other shuffles and insert/extract.

Possible known (minor?) regressions from this change are filed as:

https://llvm.org/bugs/show_bug.cgi?id=28531 
https://llvm.org/bugs/show_bug.cgi?id=30371

If something terrible happens to perf after this commit, feel free to revert until a backend
fix is in place.
