Source Map Performance

Because PostCSS needs synchronous API, we can’t move from the old `source-map 0.6 to 0.7 (many other open-source projects too).

@​7rulnik forked source-map 0.6 to source-map-js and back-ported performance improvements from 0.7. In 8.3 we switched from source-map to this source-map-js fork.

You map see 4x performance improvements in parsing map from processing step before PostCSS (for instance, Sass).

Document Nodes

Thanks to @​gucong3000, PostCSS already parse CSS from HTML and JS files (CSS-in-JS templates and objects).

But his plugin need big updates. @​hudochenkov from stylelint team decided to create new parsers for styles inside CSS-in-JS, HTML, and Markdown.

He suggested adding new Document node type to PostCSS AST to keep multiple Root nodes inside and JS/HTML/Markdown code blocks between these style blocks.
