    [deoptimizer] Preserve double bit patterns correctly. · 7376e12e
    mstarzinger authored
    This makes sure that the deoptimizer preserves the exact bit pattern of
    floating-point values (both 32-bit and 64-bit) up to the point where a
    potential {HeapNumber} is allocated. It in turn allows us to correctly
    recognize the {hole_nan_value} when stored into a {FixedDouleArray}.
