This is just a suggestion, but I think it could be worth adding the definitions
that use a multiclass separately from this `let TargetGuard = "sme2"` block. I
find it quite useful to have the multiclasses close to the definitions that use
them when reading how the builtins are defined, and when more are added here
this could become harder to follow.
