Early prototype: add an inline version to StylePropertySet, include this information to MatchedProperties

FYI this patch has its own issues that needs to be ironed out (like prevent people from abusing the logic for non-inline style StylePropertySet and causing perf regressions). I think however that the logic handles all cases of invalidation (JavaScript vs DOM). An earlier version shaved ~1% on Moz page cycler.

Comments welcome on the approach taken!
