By removing this you're effectively introducing the problem you're trying to
fix (i.e. having multiple representations of the same thing). Given
`AArch64ISD::RDSVL` exists I recommend keeping it and the lowering code for
`Intrinsic::aarch64_sme_cntsd`, which should remove the need for some of the
isel changes.
