[lit] Print slowest test first when timing tests

Browse Source 
lit supports `--time-tests` which will report the 20 slowest tests and
print a nice histogram for test times.  This change prints this list and
the histogram rows by decreasing test times.  After all, we are most
interested in the slowest tests.
