[PATCH] D53203: Allow MemoryLocation to carry pre-existing knowledge to AA to elide expensive repeated checks

MemorySSA is an analysis, all info is kept "on the side". It's standalone and no info is kept in BBs.
Some doc can be found here: http://releases.llvm.org/6.0.1/docs/MemorySSA.html

MemorySSA would be a net improvement vs MemoryDependenceAnalysis currently used in DSE.
