The custom select is because nodes with variable number of arguments (as
needed to lower ISD::CALL) didn't use to work.  I've been waiting until
that is fixed to lower calls rather than custom select them.  I have a
patch to do so sitting around, which I might get around to applying
since I think the variable arguments thing is fixed.

And without software to do something useful with all that hardware, the
hardware's nothing more than a really complicated space heater.
