Add SaveLayer-Draw-Restore optimization.
This is like SkPictureRecord's remove_save_layer1 but works with all draw calls.
Interesting patterns removed:
SaveLayer-DrawRect-Restore: Silk SKPs, desk_weather
SaveLayer-DrawPath-Restore: desk_carsvg, desk_wowwiki, tabl_androidpolice
SaveLayer-DrawPosTextH-Restore: tabl_android_police
There may be others, but I stopped looking.
