Its good that we have removed intermediate stencil blit operations using this approach.
LGTM.
jtreg/JCK all test run is fine.
J2DDemo, SwingSet2, Font2DTest is running fine in my Intel SoC Macbook pro.
RenderPerfTest : ClipFlatOval and ClipFlatOvalAA show improvement in FPS from ~13 to ~24 in my Intel SoC Macbook pro.

@aghaisas  mentioned that he is also testing on discrete GPU Macbook Pro. Lets wait for his test output.
