Going to set this aside for now.  I'd been thinking of this as a broadly applicable canonicalization to address usage of TU, but as Craig has pointed out, this is likely to be much narrower in scope due to micro-architectural differences, and the lmul=1 restriction.  Given that, likely impact isn't enough to justify pushing this right now, will return to it once larger items are addressed.
