This patch reorders the traversal of function call sites and function
formal parameters to:

- do various argument feasibility checks (`isArgumentInteresting` ) only once per argument, i.e. doing N-args checks instead of N-calls x N-args checks.

- do hash table lookups only once per call site, i.e. N-calls lookups/inserts instead of N-call x N-args lookups/inserts.
