Bug 1502751 - Don't keep a separate list of ignored-when-colors-disabled longhands. r=heycam
Most of the change is moving sets around to be static functions on LonghandIdSet. I think I like that pattern, but I can also make the new set a global static and add mako code to be `pub` or something. Though I think the LonghandIdSet::foo().contains(..) pattern is nice to read :) Differential Revision: https://phabricator.services.mozilla.com/D10653 --HG-- extra : moz-landing-system : lando
