Move clip optimizations into GrFillRRectOp
Adds a new clipToShape() virtual on GrDrawOp and implements it with
GrFillRRectOp. GrClipStack now calls this method before attempting to
clip by any other means.
Since clips are often round rects, and a round rect/round rect
intersection can itself be round rect, this allows GrFillRRectOp to
bypass clipping entirely in many cases.
