For now, we keep supporting the prefixed version, since there are examples/instructions
on the Web that don't include an unprefixed value.

Before this patch we were only optimizing the case of a single selector, which
is fine, but not enough to catch ones like .foo .bar or so.
This patch allows us to optimize classes and tags in the rightmost compound,
while keeping the current optimization for #id selectors.
Need to profile this, but code-wise should be ready for review.

Also remove specified-value-only keywords, since those are handled
only in Rust code and C++ doesn't need to know about them.

Use pixels::get_rect in CanvasData::draw_image
Those functions are the same except that get_rect isn't failible, so we
have to check that the rect we want is actually in the image.

Assign a name to iframes when loading the initial about:blank
Before, it would assign the name too late, causing scripts (which will not wait for another tick) to accidentally spawn pop-up windows instead of loading into the iframe.

Add lots of derived Debug impls
<!-- Please describe your changes on the following line: -->
Add a bunch of derived `Debug` impls. After this, pretty much anything that implements `Deserializable` also implements `Debug`. The exception is `webrender_api::RenderApiSender`, which would need a webrender PR.

Clear refcounted promise before dropping JSRuntime
Not sure if this is the right solution?
I also tried to `impl Drop for LiveDOMReferences` but it's still executed after dropping JSRuntime.
So, maybe we should clear it before dropping the JSRuntime?
