This specialization of `Bind_PlaceHolderMask` defines a mask for a `Bind` object passed recursively as a bound argument. The value is not important, as long as it is out of range. Note that `1 << 30` would be equally valid, but can lead to an overflow in constant expression with `Bind_CalcParameterMask::k_PARAM_MASK2` below (obtained by adding the masks of the bound arguments together) when there are more than 3 nested binders (this is unfortunately an error with the GNU compiler).
