db169e53e5 move annotate onto a method of UniversalRegions 
This allows it to print out the "late-bound regions" from the closure
context more easily. Besides, all the state that is being printed it
is private to the `UniversalRegions`.

9b15ddb29e remove defaulting to unit 
Types will no longer default to `()`, instead always defaulting to `!`.
This disables the associated warning and removes the flag from TyTuple

5de094e579 mir: Fix DefiningTy::Const 
Fixes #47590 by fixing the way DefiningTy represents constants. Previously,
constants were represented using just the type of the variable. However, this
will fail to capture early-bound regions as NLL inference vars, resulting in an
ICE when we try to compute region VIDs a little bit later in the universal
region resolution process.

fdc18b3067 Auto merge of #47353 - nikomatsakis:nll-issue-47189, r=pnkfelix+nmatsakis 
renumber regions in generators

This fixes #47189, but I think we still have to double check various things around how to treat generators in MIR type check + borrow check (e.g., what borrows should be invalidated by a `Suspend`? What consistency properties should type check be enforcing anyway around the "interior" type?)

Also fixes #47587 thanks to @spastorino's commit.

3b390e5420 remove bogus assertion and comments 
The code (incorrectly) assumed that constants could not have generics
in scope, but it's not really a problem if they do.

bf02c57b16 simplify UniversalRegions::to_region_vid to just consult the map

fe89f4ba86 get the DefiningTy from the body_owner_kind not type 
The type isn't a good idea because we want to treat constants
uniformly, regardless of what type of value they produce.

e9824c50ed impose inputs/ouputs on MIR after the fact 
The input/output types found in `UniversalRegions` are not normalized.
The old code used to assign them directly into the MIR, which would
lead to errors when there was a projection in a argument or return
type. This also led to some special cases in the `renumber` code.

We now renumber uniformly but then pass the input/output types into
the MIR type-checker, which equates them with the types found in MIR.
This allows us to normalize at the same time.

the type.

243bf3f718 rename "free region" to "universally quantified region" 
This has been bugging me. All the regions appear free in the source;
the real difference is that some of them are universally quantified
(those in the function signature) and some are existentially
quantified (those for which we are inferring values).
