Even if we unthrottled the invisbile animations to update the overflow region,
we don't need to send the animations to the compositor since the scroll bar
updates caused by the overflow should have been finished before sending
animations to the compositor.

This patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.
MozReview-Commit-ID: 5UQVHElSpCr
Same approach as the other bug, mostly replacing automatically by removing
'using mozilla::Forward;' and then:
s/mozilla::Forward/std::forward/
s/Forward</std::forward</
The only file that required manual fixup was TestTreeTraversal.cpp, which had
a class called TestNodeForward with template parameters :)

In FindAnimationsForCompositor(), we can ensure
EffectCompositor::GetAnimationElementAndPseudoForFrame doesn't return nullptr
since EffectSet::GetEffectSet(const nsIFrame*) at the top of
FindAnimationsForCompositor() also uses GetAnimationElementAndPseudoForFrame.

This fixes multiple things:
* EffectCompositor was using the light tree instead of the flat tree.
* When we insert an element inside the document, we may not style it right away
(we mark it for lazy frame construction with the NODE_NEEDS_FRAME). Since we
trigger animations and transitions from the traversal, we can't skip flushing
if we call getComputedStyle on any of those.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

When an animation is newly created while the same property transition is
running, the transition style rule persists until we call RequestRestyle() for
transitions level. That means if user calls getComputedStyle for the property
right after creating animation, the style obtained by getComputedStyle still
included the transitions level rule. As a result, the transitions level style
overrides newly created animation style until the next normal restyling process
happens (i.e. process transition level restyle request). Vice versa, in the
case where an animation is removed, transitions level style does not appear
until the next normal restyling.
This patch fixes this problem by trigerring a resyle of the transitions level
when an animation is created or removed.

The previous patch takes the approach that we should simply not add elements in
documents without a pres shell to EffectCompositor's set of elements to restyle.
However, there exists a case where we might have an element in a displayed
document, then we might tickle it so that it requests an animation restyle, and
then move it to a document without a browsing context. In that case we should
skip the element when we next do animation restyles.
However, even if we successfully skip the element in the document without a pres
shell, we need to make sure it eventually gets removed from the set of elements
to restyle rather than simply remaining there forever. For that reason this
patch makes us unconditionally clear the set of elements to restyle whenever we
do a full restyle from the root.
This patch also adds a test case to trigger the scenario outlined in the first
paragraph above. I have confirmed that without the code changes in this patch,
if we simply assert that target.mElement has an associated pres shell in
getNeededRestyleTarget, then that assertion will fail when running this test
case.

This patch makes us ignore animation restyle requests for elements in documents
without a pres shell made by either:
* Calls to EffectCompositor::RequestRestyle (e.g. by calling Web Animations API
methods on animations that target such elements)
* Calls to EffectCompostior::PreTraverse(dom::Element*, CSSPseudoElementType)
(e.g. by calling getComputedStyle(elem).prop on such an element).
The other overloads of PreTraverse should presumably be called during regular
document restyling where the element is expected to be in a displayed document
and hence we simply assert that that is the case for those methods.

Remove the unconditional return from FindAnimationsForCompositor(), so
we can check if there is any property running on compositor.
Also, enable a reftest and fix the mochitest expectation:
1. The expectation numbers of test_animations_omta.html in e10s and non-e10s
are different, so skip non-e10s.
2. We pass all tests in test_animations_omta_start.html with e10s;
however, got 3 test failures with non-e10s, so skip this file with
non-e10s.

We need to request an animation-only restyle to force flush all throttled
animations on main thread when we handle an event with coordinates
(e.g. mouse event).

We need to traverse rule tree to get the important rules, so we will not
override them if they have animations running on compositor.

We need this flag to avoid assertion in PostRestyleForAnimation(), which
may be called from MaybeUpdateCascadeResults() in pre-traversal.
MozReview-Commit-ID: 46AfoIUb9o3
During pre-traversal of EffectCompositor, we call MaybeUpdateCascadeResult(),
which may add new element into mElementsToRestyle, as a result, we may
iterate a mutated mElementsToRestyle. In this patch, we copy the element
which needs update cascade results into another set and traverse this new set
to call MaybeUpdateCascadeResult(). After that, do normal pre-traversal on
mElementsToRestyle.

This allows us to access metadata using `match` instead of comparison with
atoms, which makes it doable to get the pseudo-element flags in the future.
