Add an option '-# count' to run the specified test suite for a said number of times.

This is not to be used during normal test suite run, but to be used to stress test
specific test sequences repeatedly.

Example:

./dotest.py -# 3 -v breakpoint_conditions

will repeat the test suite 3 times for tests under the breakpoint_conditions directory.
