Sema does use `CK_NoOp` for those, but we don't need to re-sign function
pointers because the presence of `noexcept` on a function type doesn't change
the discriminator. The function that encodes the function type
(`encodeTypeForFunctionPointerAuth`) encodes the parameter and return types,
but ignores `noexcept`.
