    [array] Keep large array allocations on the fast path · 9eca2d3c
    Jakob Gruber authored
    Until this CL, CSA array allocation methods only handled arrays that
    could fit into new space. This behavior was preserved in a bunch
    of related builtins (e.g. Array.p.map), which completely bailed out to
    the slow path if larger allocations were required.
    
    This CL adds large object space handling to array allocation functions,
    which means that callers can use the more permissive kMaxFastArrayLength
    boundary instead of kInitialMaxFastElementsArray.
