Work in progress - add instrumentation for stubs and helper calls.

Details | Diff | Splinter Review
A useful methodology for halfmoon is to ensure there are no calls on the fast paths of any opcodes (except call opcodes, of course). This patch adds instrumentation to quickly list the hot "pitfall" opcodes -- those that use a generic stub or execute a vm helper call instead of using inlined code.
