    [heap] Implement SimulateFullSpace for PagedNewSpace · 0cd0e4bb
    Omer Katz authored
    The existing version for paged spaces simply reset the freelist, which
    doesn't work for tests that require actual objects in the space.
    The version for new space also doesn't work because it assumes
    everything after top is free space.
    
    Fill the space with FixedArray by iterating over the freelist and
    creating an object in place of each freelist entry.
    This method actually fills the space, so that we can also use it to
    force page promotion.
