    [turbofan] Properly represent the float64 hole. · 8c0c5e81
    bmeurer authored
    The hole NaN should also have proper Type::Hole, and not silently hide
    in the Type::Number. This way we can remove all the special casing for
    the hole NaN, and we also finally get the CheckNumber right.
    
    This also allows us to remove some ducktape from the Deoptimizer, as for
    escape analyzed FixedDoubleArrays we always pass the hole value now to
    represent the actual holes.
