[PATCH] D26641: [InstCombine] change bitwise logic type to eliminate bitcasts

[Sanjay Patel via llvm-commits]

Patch updated:

1. Added a check on the destination type to be an integer element type (can't do a bitwise op otherwise).
2. Added a test for that case.
3. Restricted the transform to vector types (FIXME comment in the code) pending a backend fix-up to make sure we're not creating a mess with an illegal logic op for the destination type.
