This is really part of the "recalc" rather than the "compute" work. But more to
the point, it lets us early-return on the style-sharing stuff (see the next patch).
use `::parse_non_negative instead` of `::parse` for background_size property parsing

We need to do something here to avoid a double-borrow when passing a mutable
StyleContext to match_element. After some discussion on IRC, we decided that
building the bloom filter for this case is probably worthwhile.
Ensured all font-weight keywords are preserved until computed-value time
Fixed the serialization of `font-weight` keywords (i.e. `bold`, `normal`, etc.) to ensure that Servo preserves the keyword until computed-value time (just as other major browsers do).
