It's to make switch statement in `initializeECThunks` possible. Otherwise, there is no implicit conversion from `ulittle32_t` and the switch statement would need an explicit cast. And with that cast, we wouldn't be able to use `default` far the warning. I could probably make it work, but the main motivation for having it in a public header was LLD (in #85936), changing it here felt right.
