Use a closed interval when eliminating outliers from performance measurements

Browse source 
When choosing the samples that are not outliers we use a half-open interval
(outlier_min <= x < outlier_max). This causes all of the samples to be
discarded when the interquartile range is 0 because none of them are less
than outlier_max. Fix the problem and make the test more consistent by
using a closed interval (outliner_min <= x <= outlier_max).
