This patch fixes Japanese line breaking rules before and after ruby
elements. This patch is a port of http://wkb.ug/91588 with the
following changes:
* The WebKit patch sets ruby base text to the prior context for breaks
  after the ruby. Since U+FFFD Object Replacement Character can cover
  most of the common cases that this patch does not include that part.
* canBreakBefore() is fixed to include the correct UAX#14[1] classes
  that prohibit line breaks after. The original patch is a mix of
  before and after, and lacks some important after classes.

This patch fixes the common use cases in CJK, but it's hard to say this
is the right way to fix. There are two issues that block doing so at
this moment:
1. RubyRun is LayoutBlockFlow, but after WebKit implemented, the ruby
   spec was updated to allow line breaking within ruby, so it should be
   like inline, not a replaced element.
2. The CSS WG discussed on line breaking around replaced elements, but
   the discussion is not making much progress.
Changes in this patch should be updated when these issues are resolved.

The input to the selector position and the rule position is known to
possibly overflow 12 and 18 bits respectively since the input comes from
unsigned positions into data structures known to keep more elements than
that. The selector and rule positions will be wrong regardlessly, unless
we make RuleData bigger.

Truncating the position to a max value instead of just letting it
overflow could be an option. It doesn't make sense for selector position
as trying to match any of the other selectors won't make any difference.

Truncating the rule position would make the cascading order correct when
comparing rules in the representable range with a rule outside the range,
while just letting it overflow starting from zero again will yield a
correct cascading order between two rules both outside of the
representable range.

Given that, I conclude to just remove the ASSERTs and not do anything
clever about values outside of the ranges.

The added sheets passed into StyleSheetInvalidationAnalysis may either be
added or removed. When they are removed style elements from a shadow tree,
the style element may no longer have a containingShadowRoot if the element
has already been removed. That caused a crash when the containingShadowRoot
was accessed without a nullptr check.

Instead of deducing the scope from the style element, pass the stylesheet
collection TreeScope to the analysis object. The m_scopingNodes, which is
probably a left-over from <style scoped> has been removed.

Now, the shadow tree root node, or outermost shadow host if ::content
rules makes that necessary, is always marked sub-tree dirty. The previous
code-path could trigger id/class invalidation of separate elements when
the stylesheet contents had multiple owner nodes, but that was most likely
wrong if it could ever happen.

Currently DOMWindow::navigator returns a navigator associated with a frame
even when the window is detached from the frame and another window
is attached to it. That means calling frame()->document() may return
an incorrect document, for example.

This CL makes LocalDOMWindow::navigator return a navigator with
a null frame when the window is not associated to the frame.

- Give a chance to schedule a precise GC after V8 minor and major GCs.

Otherwise, invoking WebViewFrameWidget::close() from frame swap will
result in trying to clear the frame widget on the wrong main frame.

Other miscellaneous fixes:
- WebViewFrameWidget now uses smart pointers where appropriate for its
  members.
- WebViewFrameWidget's ctor also takes a WebWidgetClient* pointer.
  This is future-proofing to help merge the widget implementations in
  WebFrameWidget and WebView.

When cleaning out a ShadowRoot's child Nodes as part of its disposal,
the child Nodes will in some cases not have other references than the
shadow root. If so, the Node will be summarily deleted without being
notified of it being removed from its DOM tree first. By calling its
removedFrom().

As a Document need to maintain an accurate attached node count, arrange
for the otherwise-unreferenced Node's document to be decremented.

The two hooks are:
* WebLocalFrame::isNavigationPending
* WebViewClient::didFirstLayoutAfterFinishedParsing

The WebLocalFrame::isNavigationPending provides a
simple check whether the content of the document intends to
change the location (via Refresh or window.location change).

The WebViewClient::didFirstLayoutAfterFinishedParsing is called
when we finish the first layout after the document had finished
parsing. Another way to explain it is "first layout after
DOMContentLoaded".

Accumulating large draw command backlogs can result in janky
performance, and in extreme cases, a GPU denial of service. This
change fixes that problem by disabling deferred rendering when
high overdraw is detected. Cases where the overdraw overwrites
the entire canvas are not affected by this change and will
stay in deferred rendering mode because overwriting the entire
canvas resets the backlog.
