Add a TraceOn(self) method to the base test class, which returns True if we are

currently in trace mode (-t to dotest.py), i.e., tracing the lldb command execution.
Change TestInferiorCrashing.inferior_crashing_python(self) to check this flag in
order to print the stack trace of the inferior thread.
