The log_call helper is now accepting a time parameter (dictionary). If the param is not None, the function will fill the timing indications (user and system time) for the TestCase. There are some TestCases whose user time is not of our interest; for example we don't really care about the cpu time of a stdout diff (MatchStdout tests). In those cases the resulting cpu time in the generated JUnit file (results.xml) will be 0.

Helper class to generate common gem5 tests using verifiers.
