Introduce a new PatternRewriter class to help keep the worklist in PatternMatcher clients up to date and provide a funnel point for newly added operations. This is also progress towards the canonicalizer supporting CFGFunctions. This paves the way for more complex patterns, but by itself doesn't do much useful, so no testcase.
