It should be easy to measure total compile times.

Reviewed by Sam Weinig.

This gives DFG::Plan the ability to track total compile times, and return them in a map
of stats that jsc.cpp can display.

I want to do some work to bring down DFG compile times. This will help me measure whether
I'm making a difference or not.
