Ah, I see. So it's specifically that you want "vmul_lane_f64(x, y, 0)"
to produce "fmul d0, d0, v0.2" rather than "fmul d0, d0, d0"?
If so, I don't think that's a property worth preserving. We were
forced into ugly scalar pseudo-vectors due to lack of global isel,
which doesn't apply here. I can't see any good reason to force the
compiler in this case: the instructions are completely
