[CompositeAfterPaint] Layout test failures because of different composited layers related to squashing

Project Member Reported by wangxianzhu@chromium.org, Aug 22 2017 
Different layer squashing methods of SPv1 and SPv2 can cause different layer tree dumps. The following layout tests are currently failing with SPv2 enabled related to squashing:

Bug(none) paint/invalidation/compositing/invalidate-when-leaving-squashed-layer.html [ Failure ]
Bug(none) paint/invalidation/compositing/invalidation-for-subpixel-offset-of-squashed-layer.html [ Failure ]
Bug(none) paint/invalidation/compositing/remove-squashed-layer-plus-move.html [ Failure ]
Bug(none) paint/invalidation/compositing/repaint-overflow-scrolled-squashed-content.html [ Failure ]
Bug(none) paint/invalidation/compositing/repaint-squashed-layer-in-rect.html [ Failure ]
Bug(none) paint/invalidation/compositing/repaint-via-layout-offset.html [ Failure ]
Bug(none) paint/invalidation/compositing/resize-squashing-layer-that-needs-full-repaint.html [ Failure ]
Bug(none) paint/invalidation/compositing/squash-partial-repaint-inside-squashed-layer.html [ Failure ]
Bug(none) paint/invalidation/compositing/squashing-inside-preserve-3d-element.html [ Failure ]
Bug(none) paint/invalidation/compositing/tricky-element-removal-crash.html [ Failure ]
Bug(none) paint/invalidation/invalidate-descendants-when-receiving-paint-layer.html [ Failure ]

Need to check if each test fails because of other bugs or runs as expected and should be rebaselined for SPv2.
