    [csa][turbofan] allow large object allocation · 343898ed
    Tobias Tebbi authored
    Add suport for large object space allocations in Turbofan and use it
    from CSA when young large objects are enabled. This maintains the
    Turbofan invariant that the generation is statically predictable.
    
    In principle, this enables write barrier elimination for large objects
    allocated from Torque/CSA. But it doesn't seem to trigger much yet,
    probably we have to improve the MemoryOptimizer.
