Avoid using getPresentationAttribute in ReferenceFilterBuilder because it is deprecated, instead use getPropertyValue. This is the last internal use of getPresentationAttribute so a follow-up patch can remove it.

When we use checkLayout() on a grid item, the results (PASS or FAIL
messages) are added as new auto-placed items in the grid. This causes
that the grid is marked as dirty which could hide bugs in the tests.

Modify the related layout tests to use a different container for the
test results. Updated expectations accordingly.

There is one test missing
"grid-item-addition-auto-placement-update.html". Which will be modified
in the patch to fix the bug in RenderGrid::addChild() (see
https://codereview.chromium.org/198703004/).

Currently, we only set a scroll parent for 
"localRootForOwningLayer".I.e., the highest
GraphicsLayer in the CLM-managed hierarchy, excluding
the squashing containment layer. But for "scroll
buddies", we need the scroll child to be the very top
of the hierarchy.

We also need to ensure that scroll buddies are not
prevented from squashing together because of the
additional "I've got a scroll parent" compositing
reason.

This cl also disables chicken-egg asserts that trip
w/ universal accelerated overflow scroll and changes
how we compute composited bounds for squashed layers
(we currently pull the bounds from the clipper, but
it picks the wrong "clipping root" in this case).

With this CL, universal accelerated overflow scrolling
and squashing work nearly perfectly modulo known hit
testing bugs (which can prevent touch scrolling) and
repaint issues (separate issue reported here
https://code.google.com/p/chromium/issues/detail?id=351790).

There's no need to constantly recompute this data. It's
already determined by the style information, so we might as
well just compute it once during style recalc.

Note: We're still computing all the direct compositing
reasons during style recalc (via updateLayerCompositingState in RenderLayer::styleChanged), but now we skip recomputing
the style determined reasons again when updating layout
and compositing. ASSERTs verify that we get the same answer
as before.

This CL reduces the amount of time spent in the compositing
update for dragging the drawer in the Polymer calculator by
3%.

It's trivial to replace the local AnimationClock in SMILTimeContainer
with the one from Document after making the observation that the only
current manipulations (updateTime/unfreeze) are already performed by
PageAnimator (DocumentAnimations::updateAnimationTimingForAnimationFrame)

Contrary to the assertions on the bug, the current code is correct. As
the user changes the selection, there will naturally be a visual
affordance to indicate the selection changes. By the time we scroll,
RL::hasBlockSelectionGapsBounds will be current and correct.

That said, the hope is that in the future paint will have no side
effects at all, nor do we want layout tests to require repaints during
their execution. So even if this is technically correct it's undesirable
on a number of levels.

This cl replaces the use of hasBlockSelectionGapsBounds with non-paint
related code (in fact, that function could be removed entirely).

Changes to the LRU lists are hidden behind a call to MemoryCache::update(), which adjusts sizes, access count, and LRU list position as appropriate. All of these are to some degree interrelated, since we keep multiple LRU lists and select one to use based access count and resource size.

MemoryCache::contains()

This CL uses some memoization to avoid unnecessary tree walking when
computing scroll parent. Why memoization and not just passing down the
values? Because sad. It turns out that we recur on the stacking tree (we
have to - squashing demands processing stuff in paint order), but we
walk up the render tree asking questions. Different tree topologies; we
could very easily visit a RenderLayer before its great great
grandparent.
