[PATCH] D45599: [SimplifyLibcalls] Memcpy + strlen propagation

[Daniel Berlin via Phabricator via llvm-commits]

GVN should already be able to get this, and if it can't, improve it's intrinsic handling (Either in  VNCoercion's memory transfer intrinsic handling, or ...).

That's gonna do a lot better than trying to special case it in libcall simplification.
It also looks like you made it O(number of instructions) worst case per call?
