Subzero: Add a few performance measurement tools.
--timing-funcs - Produces a sorted list of total time spent translating each function.
--timing-focus=<F> - Turns on the --timing equivalent just for one function. Use '*' to do this for all functions, i.e. get complete timing breakdowns across all functions.
--verbose-focus=<F> - Temporarily turns on --verbose=all for one function.
