selectors: Simplify :visited by only using the "is inside link" information.
Right now we go through a lot of hoops to see if we ever see a relevant link.

However, that information is not needed: if the element is a link, we'll always
need to compute its visited style because its its own relevant link.

If the element inherits from a link, we need to also compute the visited style
anyway.

So the "has a relevant link been found" is pretty useless when we know what are
we inheriting from.

The branches at the beginning of matches_complex_selector_internal were
affecting performance, and there are no good reasons to keep them.

I've verified that this passes all the visited tests in mozilla central, and
that the test-cases too-flaky to be landed still pass.

rust-selectors

CSS Selectors library for Rust. Includes parsing and serilization of selectors, as well as matching against a generic tree of elements. Pseudo-elements and most pseudo-classes are generic as well.

Warning: breaking changes are made to this library fairly frequently (13 times in 2016, for example). However you can use this crate without updating it that often, old versions stay available on crates.io and Cargo will only automatically update to versions that are numbered as compatible.

To see how to use this library with your own tree representation, see Kuchikis src/select.rs. (Note however that Kuchiki is not always up to date with the latest rust-selectors version, so that code may need to be tweaked.) If you dont already have a tree data structure, consider using Kuchiki itself.
