[PATCH] D51218: [GVN] Invalidate cached info for values replaced by equality propagation

I've adjusted the comment in the test case. I'm pretty sure that the part that the test is testing (that PRE is happening) is correct even if the equality propagation didn't happen, as it's based on knowing that the value of two pointers differs by a nonzero value and not anything to do with the provenance of the pointers.
