    [heap] Fix inner pointer resolution for unused young pages · ac7edc1f
    Nikolaos Papaspyrou authored
    Inner pointer resolution, to be used in conservative stack scanning,
    assumes that all pages registered with the memory allocator are
    iterable. Until this CL, this was not the case for pages that were
    owned by the young generation semispaces but were unused. Such pages
    are either in the "from" semispace, or in the "to" semispace but have
    not yet been used.
    
    This CL ensures that all pages owned by the young generation are iterable. It also adds tests to verify that inner pointer resolution
    works correctly for unused young pages and for pointers above the
    page area.
