Speed up the visited cascade by only running it for the properties that are
actually visited dependent. (These are only the properties where the separate
set of visited styles is even read at all, so running the rest is wasted work.)
MozReview-Commit-ID: 5B7wYtuH974
The style sharing cache stores the regular `ComputedValues`, so it would also
have the visited values as well for anything inserted into the cache (since they
are nested inside). Unlike all other element states, a change in state of
unvisited vs. visited does not change the style system's output, since we have
already computed both possible outputs up front.
We change the element state checks when looking for style sharing cache hits to
ignore visitedness, since that's handled by the two separate sets of values.
MozReview-Commit-ID: Dt8uK8gSQSP
Extend restyle hints to check additional cases for visited.
If we are sensitive to visitedness and the visited state changed, we force a
restyle here. Matching doesn't depend on the actual visited state at all, so we
can't look at matching results to decide what to do for this case.
This also updates the snapshot version of `match_non_ts_pseudo_class` to check
the relevant link instead of the element state, just like we do when matching
with regular Gecko elements.
There's also a separate case of a visited-dependent selector when other state or
attributes change. For this, we need to cover both types of matching we use
when cascading values. If there is a relevant link, then we also matched in
visited mode. Match again in this mode to ensure this also matches. Note that
we never actually match directly against the element's true visited state at
all, since that would expose us to timing attacks. The matching process only
considers the relevant link state and visited handling mode when deciding if
visited matches.
MozReview-Commit-ID: CVGquetQ2VW
To support visited styles, we match and cascade a separate set of styles any
time we notice that an element has a relevant link.
The visited rules and values are held in `ComputedStyle` alongside the
regular rules and values, which simplifies supporting various APIs like
`cascade_primary_and_pseudos` which expect easy access to previously matched
rules.
To simplify passing the additional values around, an additional reference to the
visited `ComputedValues` is placed inside the regular `ComputedValues`.
MozReview-Commit-ID: 2ebbjcfkfWf
Adjust the matching process to look for a "relevant link" while matching. A
"relevant link" is the element being matched if it is a link or the nearest
ancestor link.
Matching for links now depends on the `VisitedHandlingMode`, which determines
whether all links match as if they are unvisited (the default) or if the
relevant link matches as visited (and all others remain unvisited).
If a relevant link is ever found for any selector, track this as part of the
`MatchingContext` object. This is used in the next patch to determine if an
additional match and cascade should be performed to compute the styles when
visited.

[script/textinput] Fix warning: unreachable pattern
The `cfg` attribute in use resulted in two match arms for two cases on
`macos`. Since both arms had a main functionality in common, I merged
them and conditions the extra `macos` part.

Fix the -Z wr-no-batch option.
The DebugOpts struct uses the Default trait to set all the values
to false initialily. So bools in the DebugOpts struct must be
negative verbs to work correctly.
This drops the draw call count on HN from ~2000 back to ~5.

We only use whether the return value is IMPORTANT_RULES_CHANGED or not, so we
can just return true if an important rules was changed in the function.
Also, we can just return false in case of animation rules changes sine for
animation we can ensure there is no importan rules.
Because of these changes, replace_rule_node does not borrow |result| so that
we can drop a scope there.
