Daniel Berlin cd2deacac6 [MSSA] Avoid unnecessary use walks when calling getClobberingMemoryAccess 
Summary:
This allows us to mark when uses have been optimized.
This lets us avoid rewalking (IE when people call getClobberingAccess on everything), and also
enables us to later relax the requirement of use optimization during updates with less cost.
