[PATCH] D44160: [GVN] Detect fully redundant loads when we have more than one available value

[John Brawn via Phabricator via llvm-commits]

I've posted by attempt to fix this in alias anlysis in https://reviews.llvm.org/D44564, but the problem is that it's actually InstSimplify that's the underlying thing being used to figure out the value of the PHI, and that's used all over the place and causes knock-on changes that require work to be done elsewhere.
