Currently, CalcLengthOrPercentage doesn't actually keep the number
value, so if we don't treat it invalid, we can end up generating empty
`calc()` value when one contains top-level numbers (e.g. `calc(1)`),
which would violate assertion elsewhere that `calc` must not be empty.
This is not a problem for Servo, because we recovered it without much problem a
few lines below, and we never reached the pathological case where the filter has
one element (the root), and we restyled another element with depth 1.
Fixes bug 1321725.

transition is the same as the end value for a running transition per
CSS-TRANSITIONS § 3.
Besides being contrary to spec, the old behavior could cause a cascade
of CSS transitions incorrectly triggering themselves when calls to
`getComputedStyle()` were intermingled with them.
Improves performance of nytimes.com.

failing test for correct to_css of "width"
separate test for mq and to_css
implement css serialization for Eq
remove PASS test expectation
remove FIXME
simplify serialization
I realized that I fixed this issue incorrectly when the test failed before. Our design
document specifies that restyle hints must be expanded by the parent before traversing
children, so that we can properly apply LaterSiblings restyle hints. This includes
parents that do not themselves need processing (StylingMode::Traverse).
So we need to preprocess children even in the case where we don't restyle the parent.
On the flip side, we do in fact know whether a child needs processing before enqueuing
it, so we can skip the conservative visit I added before.

This also changes the algorithm to match w3c/csswg-drafts#754 instead of
the current cssom draft, because that makes the code simpler and matches
implementation of other browsers.
