Use general instruction/stack pointer convenience method instead of manually

Use general instruction/stack pointer convenience method instead of manually
finding the instruction/stack pointer for exploitability rating.

There was already a method that found the instruction pointer, so the files
for exploitability ratings had repeated code. Also a method for finding the
stack pointer is implemented in this CL.
