You are right, `EltTypeBool128` is not used right now; I can remove it. When we
started working on the pre-ACLE intrinsics in our downstream compiler, we were
planning to add something like `svptrue_b128`, even though the hardware `PTRUE`
instruction doesn't support the Q size specifier. It is still not clear to me
how the ACLE wants users to create a predicate vector for a call to a `_za128`
intrinsic.
