This patch adds a timing capability that shows the clock times and percentages for phases of the TableGen frontend and appropriately instrumented backends. It is requested with the --time-phases option.

I instrumented about five backends and will continue to instrument more of them over time.

I removed an old timing feature that was only used by one backend.
