[PATCH] D50339: Consistently use MemoryLocation::UnknownSize to indicate unknown access size

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added a comment.

The practical application of this is to indicate aliasing with a given memory object, but without specifying exactly which part of the object is accessed (since it may be unknown).  Dropping memory operands altogether will alias the operation with all other objects, so it will be correct, but overly conservative.
