When dumping the session log for a failed/errored test, also emit the command to

invoke the test driver to rerun the very same test.  Example output:

/Volumes/data/lldb/svn/trunk/test $ tail 2010-11-09-14_51_34/ExpectedFailure-TestSettings.SettingsCommandTestCase.test_set_output_path.log 

Traceback (most recent call last):
  File "/Volumes/data/lldb/svn/trunk/test/settings/TestSettings.py", line 136, in test_set_output_path
    "'stdout.txt' exists due to target.process.output-path.")
AssertionError: False is not True : 'stdout.txt' exists due to target.process.output-path.


To rerun this test, issue the following command from the 'test' directory:

./dotest.py -v -t -f SettingsCommandTestCase.test_set_output_path
