Victor Hernandez 2491ce0353 Fix bug where array malloc with unexpected computation of the size argument resulted in MallocHelper 
identifying the malloc as a non-array malloc.  This broke GlobalOpt's optimization of stores of mallocs 
to global variables.

The fix is to classify malloc's into 3 categories:
1. non-array mallocs
2. array mallocs whose array size can be determined
3. mallocs that cannot be determined to be of type 1 or 2 and cannot be optimized

getMallocArraySize() returns NULL for category 3, and all users of this function must avoid their 
malloc optimization if this function returns NULL.

Eventually, currently unexpected codegen for computing the malloc's size argument will be supported in
isArrayMalloc() and getMallocArraySize(), extending malloc optimizations to those examples.
