FIX problem where we were incorrectly putting the prefix of the list into the "suffix" list.

Fix problem where we accidentally returned KeepPrefix instead of KeepSuffix!

Speed up convergence significantly and also reduce the size of testcases by making large portions of a function's CFG dead at a time.

We were not actually deleting any functions from the module!
