Discard the first measurement obtained in case it has been tainted
somehow by cold caches or other adverse circumstances.
Motivation
Benchmark have traditionally discarded outliers . Since we do not have robust outlier detection at this time, we will start by simply discarding the first measurement as it is most likely to be tainted by cold caches, etc.
