[PATCH] D114126: [PatternMatch] Create match method to track uses complexity. WIP.

Taking a step back here, I want to ask: Is this solving some kind of real problem? I get the impression that use counting in InstCombine has moved beyond a practical consideration into the realm of religious dogma. I don't think there is much value in always making exotic, complex folds maximally applicable in multi-use scenarios, if doing so does not happen to be straightforward.
