Sanjay Patel 20e9431b19 [InstCombine] change select type to eliminate bitcasts
This solves a secondary problem seen in PR6137:
https://llvm.org/bugs/show_bug.cgi?id=6137#c6

This is similar to the bitwise logic op fold added with:
https://reviews.llvm.org/rL287707

And like that patch, I'm artificially restricting the
transform from vector <-> scalar types until we're sure
that the backend can handle that.

dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
