George Burgess IV 510f86ea5c [MemorySSA] Fix def optimization handling ... In order for more complex updates of MSSA to happen (e.g. those in D45299), MemoryDefs need to be actual `Use`s of what they're optimized to. This patch makes that happen. In addition, this patch changes our optimization behavior for Defs slightly: we'll now consider a Def optimization invalid if the MemoryAccess it's optimized to changes. That we weren't doing this before was a bug, but given that we were tracking these with a WeakVH before, it was sort of difficult for that to matter. We're already have both of these behaviors for MemoryUses. The difference is that a MemoryUse's defining access is always its optimized access, and defining accesses are always `Use`s (in the LLVM sense). Nothing exploded when testing a stage3 clang+llvm locally, so... This also includes the test-case promised in r340461. llvm-svn: 340577		2018-08-23 21:29:11 +00:00
