Mike Gerwitz 9990be58a7 tamer: Lower sum expressions
This was a fairly simple addition, since rate blocks already lower into sum
expressions; these are just non-identified.

This does emphasize that the nir::parse `ele_parse!` abstraction I spent so
much time on ended up not being a perfect fit, as it now has some
boilerplate after it was stripped of much of its capabilities some time ago.

Don't worry, `nir::air` and `asg::graph::xmli` will get cleaned up.

Mike Gerwitz 82915f11af tamer: asg::graph::object::xir: Initial rate element reconstruction
This extends the POC a bit by beginning to reconstruct rate blocks (note
that NIR isn't producing sub-expressions yet).

Importantly, this also adds the first system tests, now that we have an
end-to-end system.  This not only gives me confidence that the system is
producing the expected output, but serves as a compromise: writing unit or
integration tests for this program derivation would be a great deal of work,
and wouldn't even catch the bugs I'm worried most about; the lowering
operation can be written in such a way as to give me high confidence in its
correctness without those more granular tests, or in conjunction with unit
or integration tests for a smaller portion.
