Optimize GrOpsTask::onIsUsed
Before this CL, the render task clustering algorithm was taking
a ton more CPU time than needed by visiting proxies every
time it needed to check for surface usage.
Note also, the fSampledProxies does indeed usually contain many
duplicates in our SKPs. Sometimes 3 or 4x. I may experiment with
using a hash set as suggested by a comment.
