    {FreePages} is never expected to fail, and each caller wraps the call in
    a CHECK macro. In order to learn more about failures, this CL moves the
    CHECK inside of {::FreePages}, to fail whenever the {PageAllocator}
    fails to free pages.
    
    As a next step, I'll audit our {PageAllocator} implementations to ensure
    that none of them return {false} for {FreePages}. Note that this is
    already the case for the gin platform (chromium).
