I was thinking about ways to reduce the overhead created by this change. I came up with D57367 <https://reviews.llvm.org/D57367>, which is an alternative that focuses on nodes likely to benefit from the change instead of the whole DAG. It misses several opportunity that exist in that patch, but it seems to be a tradeof worth doing.
