ArraySize * ElementSize ElementSize * ArraySize ArraySize << log2(ElementSize) ElementSize << log2(ArraySize) Refactor isArrayMallocHelper and delete isSafeToGetMallocArraySize, so that there is only 1 copy of the malloc array determining logic. Update users of getMallocArraySize() to not bother calling isArrayMalloc() as well. llvm-svn: 85421
