r? @folkertdev
Not my area of expertise, can you review this?

folkertdev

Looks good to me but let's give others a bit of time to also take a look.

                if allow_experimental_reg {
                    types! {
-                        lasx: F16, F32, F64,
+                        lasx: I128, F16, F32, F64,


out of interest, will you add f128 to this set too?

Thanks! I don't think so. Neither LSX nor LASX supports the f128 type.
