[PATCH] D133036: [InstCombine] Treat passing undef to noundef params as UB

[Martin Storsjö via Phabricator via cfe-commits]

FYI, this change broke Wine (at least on arm and aarch64). Not saying that it is legit breakage of code that actually was UB to begin with though - it's going to take some time to figure out what's broken though.
