Sanjay Patel e930b092c4 [InstCombine] morph an existing instruction instead of creating a new one ...

One potential way to make InstCombine (very slightly?) faster is to recycle instructions 
when possible instead of creating new ones. It's not explicitly stated AFAIK, but we don't
consider this an "InstSimplify". We could, however, make a new layer to house transforms 
like this if that makes InstCombine more manageable (just throwing out an idea; not sure 
how much opportunity is actually here).
