This PR reviewed by emilio and xidorn on bugzilla. That is backed out because of Windows build problems. Fixed and landing it again.

The tests are designed for this, and trying to accommodate 32-bit
platforms is difficult. Size concerns due to element packing and holes
are less of a problem on 32-bit platforms in any event.
The @font-feature-values declaration identifiers are asci case insensitive.
We should convert all of them to lowercase to be able to reduce the same
declarations. Also gecko stores them as lowercase in gfxFontFeatureValueSet.
We can't use a slice anymore, because the input might be the VecDeque from the
sequential traversal, which requires an iterator to handle the ring buffer.

This has two advantages:
* It allows us to store nodes in the same format that the parallel traversal uses.
* It allows us to double the size of the sequential work queue without increasing
the storage, which allows us to have WORK_UNIT_MAX * 2 entries before heap-
allocating, which is about what we want for adaptive mode.

We could use this method to convert a TransformList into a Matrix, and
use this matrix for computing distance for Stylo and rendering the transform
for Servo.
This is an equivalent of nsStyleTransformMatrix::ReadTransforms in Gecko.

Remove unused selector visitor argument.
The real win here is avoiding cloning the iterator when nobody actually uses it.

Try to update running CSS animations when CSS rules are changed.
In the case where values in CSS rules changed directly by CSSOM, the old
value in the CSS rule block is immediately replaced by the new one. So if
the element, which is applied to the CSS rule, has running animations, the
new value is used during cascading process in animation-only restyle. Thus
in a subsequent normal restyle, we can't tell whether the value in the CSS
rule has changed or not. As a result, transitions may not be triggered
(bug 1393323) and CSS animations may not be cancelled if the updated
animation-name is 'none' (bug 1392851).
For the latter case of CSS animations where animation-name has been updated to
'none', this patch introduces a workaround whereby we trigger an update of
running animations whenever the traversal is triggered by changes to CSS rules
and we have existing CSS animations.
