[igt-dev] [PATCH i-g-t 5/8] trace.pl: Context save only applies to last request of a bunch

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

Skip accounting the context save time for anything but the last request of
the coalesced bunch, and also skip drawing those boxes on the timeline.
