There's only one case of sync frame construction from ContentRemoved now, and
it's not on the element being removed, but on the whitespace siblings if needed,
and _only_ when they don't support lazy frame construction.
Basically, this switches all the RecreateFramesForContent calls to use
`aAsyncInsert` (which I changed to an enum class for readability), except when
we're already reframing.
Also, it switches ReframeTextIfNeeded to opt-in into lazy frame construction,
since it's used only when aFlags == CONTENT_REMOVED.
This allows to simplify the DestroyFramesFor API (which I'm happy to rename to
something more meaningful, since now it's something like
DestroyFramesForAndRecreateThemAsync), and do some other consistency cleanups.
A bunch of the ContentRemoved callsites were pretty random at passing
aAsyncInsert, and that was some kind of a mess. This patch ensures consistency,
and makes it impossible to do O(n^2) work when removing DOM nodes, which is
nice.
The underlying reason for this is explained in the description of bug 1377848,
and basically allows us to remove a bunch of Servo hacks on the longer term (a
few of them are going away already, yay!).

CSS animations / transitions and element.animate animations of opacity will
still be treated as animations.
JS-implemented opacity animations will no longer be detected as animations.
I hope that's fine. The current heuristic makes us detect opacity 'animations'
in lots of cases where there isn't an actual animation, and the resulting
layerization changes from those detected animations cause expensive repaints.

In case of pseudo element, AnimationsWithDestroyedFrame holds the parent
element instead of generated pseudo content, so the primary frame of the
holding content is not the primary frame for pseudo elements. We need to
check correct primary frame respectively.

Adds another restyle generation which represents the dirty state of raw
style changes, so that getComputedStyle() wont be confused by optimizations
made by style engines.

Container is the result of dereferencing a non-null variable, so there's no way
that can be null.

This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those
required by the changes described above).
- Fixes a bunch of labels that had gotten out of sync with the name of the
class and/or function that encloses them.
- Removes a useless PROFILER_LABEL use within a trivial scope in
EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving
any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.
- Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is
done within them, instead of at their callsites, because that's a more
standard way of doing things.

As I've said before, as module owner I prefer that MOZ_ASSERT_IF not be
used in the module because I consider it to be unreadable. However, a
few uses have crept in, and this patch removes them.
I consider it to be unreadable because the name looks like a name that
uses smalltalk-ish naming conventions, i.e., with a part of the name
corresponding to each parameter, in order. However, the parameters are
in the order opposite the name.
This was written primarily with the vim commands:
:%s/MOZ_ASSERT_IF(\([^,]*\),/MOZ_ASSERT(!\1 ||/
:wn
followed by manual cleanup for indentation and removal of !!.

This is less expensive than sending nsChangeHint_AllReflowHints, and it should
be sufficient since hiding/showing scrollbars is basically just changing the
available space.

Some changes to animations don't affect the computed style and yet still
require the layer to be updated. Therefore, we also need to call
AddLayerChangesForAnimation in ServoRestyleManager. In this patch, we
factor out this function from GeckoRestyleManager, so we can reuse it.

This protects all accesses to the frame property table with a bit stored
on the frame. This means we avoid hashtable operations when asking
about frame properties on frames that have no properties.
The changes to RestyleManager, and the new HasSkippingBitCheck API, are
needed because RestyleManager depended on being able to ask for
properties on a deleted frame (knowing that the property in question
could not have been set on any new frames since the deleted frame was
destroyed), in order to use the destruction of the properties that
happens at frame destruction as a mechanism for learning that the frame
was destroyed. The changes there preserve the use of that mechanism,
although it becomes a bit uglier. The ugliness is well-deserved.
