Driver: Make argument parsing fast.

On a synthetic command line consisting of almost all defined options,
this drops wall time from .00494 to .00336 and user time from .00258
to .00105.

On the same benchmark, clang-driver is about 15% faster than the
primary gcc driver and almost twice as fast as the gcc driver driver.
