Chandler Carruth 464bda3a16 Teach the reassociate pass to fold chains of multiplies with repeated ... elements to minimize the number of multiplies required to compute the final result. This uses a heuristic to attempt to form near-optimal binary exponentiation-style multiply chains. While there are some cases it misses, it seems to at least a decent job on a very diverse range of inputs. Initial benchmarks show no interesting regressions, and an 8% improvement on SPASS. Let me know if any other interesting results (in either direction) crop up!
