New Revision: 122264

URL: http://llvm.org/viewvc/llvm-project?rev=122264&view=rev
Log:
Add a new convenience pass for testing InstructionSimplify.  Previously
it could only be tested indirectly, via instcombine, gvn or some other
pass that makes use of InstructionSimplify, which means that testcases
had to be carefully contrived to dance around any other transformations
that that pass did.
