I'm going to apply patches 1-19 and 22 (that's up to
"3-reg-same VMUL, VMLA, VMLS, VSHL", plus the "move gen function
typedefs" patch) to target-arm.next as they've been reviewed.
That will leave the 3-reg-same in a partially converted state
but it is not too confusingly so (or at least not much more
so than having the rest of the neon-dp group unconverted) and
I think that it will be easier to deal with this series and
the rest of the conversion if we get the completed parts into
the tree sooner rather than later.
