This CL: 1) removes the EXPERIMENTAL_optimize on SkCanvas & SkDevice 2) moves the saveLayer gathering step to endRecording 3) Replaces GPUOptimize with SkRecordComputeLayers 4) Update bench_pictures & render_pictures to provide the new flag #2 also necessitated moving the BBH computation (and record optimization) out of SkPicture's ctor (and into endRecording) Review URL: https://codereview.chromium.org/718443002
