DescriptionIncrease load of blink_perf.paint to reduce flakiness
We measure frame time so the granularity of frame cycle affects the
accuracy (small load sometime causes 1 cycle flakiness) and visibility
(performance difference of a too small load is hidden by the smallest
frame cycle) of the results. See https://goo.gl/wGEsdM for samples of
the flakiness.
Increase load to avoid the above issues, especially after we excluded
GC time from the measured time (https://codereview.chromium.org/2559893002/)
for crbug.com/667811.
Now most of the measured times on my local Linux machine are between
100ms and 300ms.
Modified some tests to avoid the increased load from causing too much
layout time.
NOTRY=true (try bots help nothing for this CL)
