Specifically, don't bother to collect "-timing" and "-szstats" information since they anyway don't get printed out under the MINIMAL build. This is done by using the ALLOW_DUMP flag to guard whether code and timing stats are collected. This ends up reducing the native translator size by about 3%. ALLOW_DUMP is used as the guard since it already guards the output of the collected data - no sense collecting the data if it can never be printed out.
To minimize the number of ALLOW_DUMP tests, we push the tests into the timing/stats class methods.
