SPv2: compositor-independent-transform-cancel.html animations aren't composited.

Project Member Reported by wkorman@chromium.org, Mar 16 2017

Issue description

This is a standard case where the test aims to test composited animations that are dynamically constructed, but they have no content. For SPv2 we require content for them to be composited.

Adding content as an 'x' within the constructed div produces a new failure that looks like a bug in the wtf hash impl for CompositorElementId added in http://crrev.com/2724083002 which is entirely believable as I made only a rudimentary initial impl effort there.

[1:1:0316/134612.036389:2936174680863:FATAL:HashTable.h(1375)] Check failed: !isDeletedBucket(*(lookupForWriting(Extractor::extract(entry)).first)).

#10 0x7fb172713dfa blink::PaintArtifactCompositor::update()

 
Also the case for composited-animation-independent-transform-cancel.html
Hacking CompositorElementIdHashTraits so that deleted-value = (-1, -1) which may be more the correct business as it were produces failed DCHECK as:

[1:1:0316/135928.785524:2936971430198:FATAL:PropertyTreeState.cpp(44)] Check failed: expectedElementId == actualElementId ((19, 0) vs. (2, 0))

which could be the same underlying bug as  http://crbug.com/702350
