0b15a66a80 account for the pick-constraint edges when reporting errors 
Also, thread through better span info to improve the error message to
something tolerable.

4831146afa remove outdated TODO markers 
These were left behind to remind me to cleanup the code -- but the
relevant cleanups were already done.

4de99600b0 add a FIXME related to the non-free-region case 
I don't think it would actually be harmful to just ignore such cases
but I'm inclined not to take chances.

4c91bb9571 introduce a VecGraph abstraction that cheaply stores graphs 
This is perhaps better than the linked list approach I was using
before. Lower memory overhead, Theta(N+E) storage. Does require a
sort. =)

The constraint set is going to be more than just a set of outlives
constraints.
