Peter Collingbourne 5c78f7db18 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.
