Fix integration tests logfile issues (Valgrind)
The Valgrind integration test has checks to make sure the number of expected logfiles match the number of observed logfiles. (To check that we aren't missing any Valgrind error output.) There are a number of integration tests which don't pass this check. This is mostly because of accidentally overwriting log files, or otherwise dumping/ignoring the output.
This also includes some updates to the heuristics themselves, to better support some use cases (running programs from within a loop), as well as to permit the testing server to track the logfile failures on a subtest-by-subtest basis.
