Nadav Rotem 5d4e205874 MemoryDependenceAnalysis attempts to find the first memory dependency for function calls. 
Currently, if GetLocation reports that it did not find a valid pointer (this is the case for volatile load/stores),
we ignore the result. This patch adds code to handle the cases where we did not obtain a valid pointer.
