🔬This is a nightly-only experimental API. (core_intrinsics)

Does a three-way comparison between the two arguments, which must be of character or integer (signed or unsigned) type.

This was originally added because it greatly simplified the MIR in cmp implementations, and then LLVM 20 added a backend intrinsic for it too.

The stabilized version of this intrinsic is Ord::cmp.
