Rebaselines for https://codereview.chromium.org/748853002

Add support for hoisting layers in pictures drawn with a matrix - https://codereview.chromium.org/748853002 changed the following GMs:

multipicturedraw_sierpinski_tiled
multipicturedraw_rrectclip_tiled
multipicturedraw_rectclip_tiled

Note that it also, somewhat mysteriously, "fixed" the rendering bugs in some of the S4's multipicturedraw images (see skia:3116).
