leak the affects of closures on the free-region-map, like we used to
...
This restores the behavior of regionck with respect to the
free-region-map: that is, it collects all the relations from the fn
and its closures. This feels a bit fishy but it's the behavior we've
had for some time, and it will go away with NLL, so seems best to just
keep it.

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.

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.
