Original issue's description:
> Traverse PDF page tree only once in CPDF_Document
>
> In our current implementation of CPDF_Document::GetPage, we traverse
> the PDF page tree until we find the index we are looking for. This is
> slow when we do calls GetPage(0), GetPage(1), ... since in this case
> the page tree will be traversed n times if there are n pages. This CL
> makes sure the page tree is only traversed once.
>
> Time to load the PDF from the bug below in chrome official build:
> Before this CL: 1 minute 40 seconds
> After this CL: 5 seconds
