MemorySSA: Revert r269678 and r268068; replace with special casing in MemorySSA. It turns out that too many passes are relying on alias analysis results for control dependencies. Until we fix that by introducing a more accurate modelling of control dependencies, special case assume in MemorySSA instead. Also introduce tests to ensure we don't regress the FunctionAttrs or LICM passes. Differential Revision: http://reviews.llvm.org/D20658 llvm-svn: 270823
