Nit: in this case it's `float128`. The `long double` variant of `setpayload` isn't enabled yet.

```suggestion
    // Essentially this:
    //   T nan_payload = T(FPBits::FRACTION_MASK >> 1);
    // but won't try to cast from BigInt to a floating-point type on RISC-V,
    // which supports float128 but not 128-bit ints.
