[InstCombine] LogicOpc (zext X), C --> zext (LogicOpc X, C) (PR28476)
The benefits of this change include:
1. Remove DeMorgan-matching code that was added specifically to work-around
the missing transform in http://reviews.llvm.org/rL248634.
2. Makes the DeMorgan transform work for vectors too.
3. Fix PR28476: https://llvm.org/bugs/show_bug.cgi?id=28476
Extending this transform to other casts and other associative operators may
be useful too. See https://reviews.llvm.org/D22421 for a prerequisite for
doing that though.
