bf9d6e5c37 TBAA: remove !tbaa from testing cases when they are not needed. 
This will make it easier to turn on struct-path aware TBAA since the metadata
format will change.

83ba06afa8 Clear unknown mem ops when merging stack slots (pr14090) 
When merging stack slots, if StackColoring::remapInstructions gets a
value back from GetUnderlyingObject that it does not know about or is
not itself a stack slot, clear the memory operand in case it aliases
the merged slot. This prevents the introduction of incorrect aliasing
information.
