Thanks for taking a look at this :) I tried your suggestion of adding ImmAr<Op> 
to the list of properties here but had some problems with it (i.e. Cannot 
select: intrinsic %llvm.aarch64.sve.fmlalb.lane). I don't think this is too 
much of an issue here as we have additional checks on the immediate with 
VectorIndexH32b, which ensures the immediate is in the correct range.
