Interesting, though after peeking at it, I guess I shouldn't be surprised.
Essentially we may want to be more aggressive about steering sub-word things to
PLUS for rv64. The key issue is if we have a SImode AOP operation that feeds
an SI->DI extension, then steering to PLUS allows us to use the addw form to
swallow the extension.
I need to do a bit more testing, but yea, there's something real in here.
