run-perf-tests --profile option should cause tests to run in one DRT instead of 4

After the recent change to have RPT restart DRT after 5 runs instead of using one DRT for all 20 runs, the --profile output is more of a pain to deal with.

Most notably is using run-perf-tests --profile with a directory, now is unreadable (since easy test prints out 4 blocks of text instead of 1).  --profile used to be very nice with a directory on Linux (where it can summarize with the top 10 hottest symbols).  On Mac this is little change, as it makes no attempt to summarize since we can't parse the instruments data at the command line.  On all systems it's now producing 4 profiles for a test instead of 1, which is sub-optimal.

Even just running 5 runs instead of 20 (and thus one copy of DRT) in --profile mode would be better than current behavior.
