[PATCH] D18718: [DependenceAnalysis] Check if result of getConstantPart is null

A seg-fault occurs due to a reference of a null pointer, which is the value returned by getConstantPart. This function returns null if the constant part is not found. The code that calls this function needs to check for the null return value.
