Original issue's description:
> Make the HTMLDocumentParser yield more aggressively
> 
> Based on eseidel@'s CL: https://codereview.chromium.org/258013009/
> 
> Before this CL,
> HTMLDocumentParser::didReceiveParsedChunkFromBackgroundParser
> parsed the received chunk inline.
> This was problematic because the function is invoked in IPC priority,
> and DOM construction can block other time critical tasks.
> 
> This CL stops inline parsing and didReceiveParsedChunkFromBackgroundParser
> is changed to always defer the processing.
> 
> Note that this also changes how HTMLPreloader is scheduled.
> Before this CL, the preloader was not invoked when pump was done inline
> from didReceiveParsedChunkFromBackgroundParser.
> However, this CL ensures that the preloader is always invoked for all
> confirmed tokens so that resource loading would not be delayed from
> running slow synchronous scripts. This CL also delays the preloader
> invocation until appcache is initialized, so that preloader requests would
> respect it.
> 
> Rebaselines due to preloader being invoked more eagerly:
