Sanjay Patel e359eaaf70 [InstCombine] change bitwise logic type to eliminate bitcasts ... In PR27925: https://llvm.org/bugs/show_bug.cgi?id=27925 ...we proposed adding this fold to eliminate a bitcast. In D20774, there was some concern about changing the type of a bitwise op as well as creating bitcasts that might not be free for a target. However, if we're strictly eliminating an instruction (by limiting this to one-use ops), then we should be able to do this in InstCombine. But we're cautiously restricting the transform for now to vector types to avoid possible backend problems. A transform to make sure the logic op is legal for the target should be added to reverse this transform and improve codegen.
