Chad Rosier ec89db7971 Add a boolean parameter to the ExecuteAndWait static function to indicated
if execution failed.  ExecuteAndWait returns -1 upon an execution failure, but
checking the return value isn't sufficient because the wait command may
return -1 as well.  This new parameter is to be used by the clang driver in a
subsequent commit.
