Original issue's description:
> Split out CSSParser public API
> 
> This patch separates the public API of BisonCSSParser from the hundreds
> of public methods it exposes. The plan is to build a new parser based on
> the css-syntax specification, which will eventually complete replace the
> bison-based parser. The functions in this class will do the run-time
> switching between the bison parser and the new (unwritten) parser.
> 
> For the functions here which are only ever used with a newly instantiated
> BisonCSSParser, I've moved instantiation to inside the CSSParser so that
> the functions can be static.

Did you file a bug about the compile errors or the CQ landing patches which
break compile?
