[perf] Print min_ticks in report
As the change and ranking is based on the min_ticks, and as this can
sometimes deviate wildly from median_ticks, include min_ticks in the
output.
In particular it helps to explain cases like:
xlib-rgba rectangles_similar-rgba-mag_source-512 10.13 88.41% -> 5.77 0.19%: 1.50x slowdown
which becomes
xlib-rgba rectangles_similar-rgba-mag_source-512 3.83 (10.13 88.41%) -> 5.75 (5.77 0.19%): 1.50x slowdown
(Considering the poor standard deviation on the initial measurement, this
is more likely a sampling error than a true regression.)
