I wonder if actually this is better named as GetAArch64SVEProcessedOperands because if we have to choose a name that's common to both the SME and SVE builtins, choosing SVE might make more sense. That's because we're specifically dealing with scalable vectors in general here and not something that's intrinsically linked to SME.
