Generate "invalidates" facts when -Znll-facts is passed
Most of the new code is copied directly from the heart of the MIR borrowchecker. I was expecting more fundamental structural changes, hence the copying. This appears to work as it stands, but I'd like to submit a follow-up PR to reduce code duplication. I figured that could wait though, since this is blocking a large amount of work in the borrow check repository and I'm out of time for tonight =).

stop considering location when computing outlives relationships
This doesn't (yet?) use SEME regions, but it does ignore the location for outlives constraints. This makes (I believe) NLL significantly faster -- but we should do some benchmarks. It regresses the "get-default" family of use cases for NLL, which is a shame, but keeps the other benefits, and thus represents a decent step forward.

rework causal tracking to explore outlives relationships
...
Instead of tracking the "cause" of each bit that gets added, try to
recover that by walking outlives relationships. This is currently
imprecise, since it ignores the "point" where the outlives relationship
is incurred -- but that's ok, since we're about to stop considering that
overall in a later commit. This does seem to affect one error message
negatively, I didn't dig *too* hard to find out why.
