5592bb7c33 MIR-dump: print return type from local_decls for _0 
We've kind of got the same information twice in the MIR, between the
return-type field and the local-decls. Seems un-great.

109c9a79ed infer: extract total number of region variables from infcx 
We are heading towards deeper integration with the region inference
system in infcx; in particular, prior to the creation of the
`RegionInferenceContext`, it will be the "owner" of the set of region
variables.

adf1519941 make the region_constraints field an Option 
This way, we can `take()` ownership of it when we are going to resolve regions.

15a2dfa324 move the OutlivesEnvironment into infer so that nll can use it 
Unquestionably there is more cleanup to be done, but I'm not sure what
it should look like yet, so leaving it roughly as is.

3cc44a569d do not invoke required_region_bounds in region_obligations 
Instead, just search the param env predicates directly. This is
equivalent to what we were doing before but more efficient.

e0630e8683 refactor how we extract outlives bounds from trait definitions 
This new way is **slightly** less expressive (I would be shocked if it
affects any code, though) when it comes to higher-ranked bounds or a
few other weird tricks. But we don't handle those consistently
regardless, and the new way does not require normalization and is just
wildly simpler.
