Pete Cooper 92a55e80b8 Fix IfConverter to handle regmask machine operands. 
A regmask (typically seen on a call) clobbers the set of registers it lists.  The IfConverter, in UpdatePredRedefs, was handling register defs, but not regmasks.

These are slightly different to a def in that we need to add both an implicit use and def to appease the machine verifier.  Otherwise, uses after the if converted call could think they are reading an undefined register.

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.
