[MemCpyOpt] Regnerate test checks (NFC)

[MemCpyOpt] Remove MemDepAnalysis-based implementation The MemorySSA-based implementation has been enabled for a few months (since D94376). This patch drops the old MDA-based implementation entirely. I've kept this to only the basic cleanup of dropping various conditions -- the code could be further cleaned up now that there is only one implementation.
