I'm going to apply this patch to target-arm.next because
my refactoring of Neon hasn't got to this group of insns
yet, so putting the fix into the tree is the easiest way
to remind me to handle it during the refactoring.
(The other patch is in code I've already refactored; I'm
planning to send out a series with that refactoring shortly.)
thanks
