Changes to scala bench.
Fixed the time reporting in PC.c
Some more simplifications to the scala bench
Added cold and warm run benching to the scala bench.
added worst case bench time to the scala version of the bench
Added recording of the bench number that the worst-case time occurred on.
Added seed randomization for each bench to make sure the JIT doesn't optimize away important sections of the bench. The results are still consistent, they're just consistent across the bench results as a group instead of per bench.
