Seems to be a 38% layout win on a site I tested with a lot of text.
Other browser engines typically do not duplicate the information in the font style struct. `FontStyle` actually predates @SimonSapin's CSS selector matching library. It's time to get rid of it!

`Node.unsafe_get_flags()` returns `*const NodeFlags`, but `NodeFlags` has only `u8` length.
So We should just returns a raw value instead of any pointers.
This fixes#3248.
r? @jdm. Please review for mistakes mercilessly! Also, I got a host of test failures when running the worker tests, not sure if these tests are expected to pass locally or not.
This implements fragment merging, in order to incrementally reflow linebroken
text. This makes the `whitespace_pre.html` reftest pass with incremental reflow
turned on with `-i`.

This type simply wraps `RefCell<T>` to add the special method,
and introduce the method to return the pointer of the value contained in
itself, for used in layout task.
Now that DOM/Flow traversals have been refactored out, the `recalc_style_for_subtree`
function in `css/matching.rs` can be removed, in lieu of just running the standard
`recalc_style_for_node` and `construct_flows` traversals sequentially. Now we
no longer have the maintenance headache of duplicating selector matching logic
in two places! \o/
This passes reftests with both default arguments, and with `-y 1`.

This also hides the not-yet-working parts of incremental reflow behind a runtime
flag. As I get the failing reftests passing, I'll send pull requests for them one
by one.

Column spans are not yet supported.
This effectively adds support for percentage widths, and it also fixes
many bugs, improving the layout of Google and Wikipedia.
This implements a general framework for legacy presentational attributes
to the DOM and style calculation, so that adding more of them later will
be straightforward.
