Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static

and T->isPointerTy(). Convert most instances of the first form to the second form.

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.

For now this only computes the allocated size of the memory pointed to by a
