Rollup merge of #53315 - nikomatsakis:newtype-index, r=Mark-Simulacrum 
use `NonZeroU32` in `newtype_index!`macro, change syntax

Various improvements to the `newtype_index!` macro:

- Use `NonZeroU32` so that `Option<T>` is cheap
- More ergonomic helper method, no need to import `Idx` trait all the time
- Improve syntax to use `struct` keyword so that ripgrep works to find type def'n

Fixes https://github.com/rust-lang/rust/issues/50337

I'm curious to see if this passes tests =)

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`.

Don't reduce E0161 to a warning in NLL migrate mode

This error has been on stable for a while, and allowing such code cause the compile to later ICE (since we can't codegen it). Errors `box UNSIZED EXPR` with unsized locals because it's not compatible with the current evaluation order (create the box before evaluating the expressions).

cc #53469 (fixes the ICE in this case)

8785e348ba Auto merge of #53580 - nikomatsakis:nll-issue-53568, r=pnkfelix 
fix NLL ICEs

Custom type-ops reuse some of the query machinery -- but while query results are canonicalized after they are constructed, custom type ops are not, and hence we have to resolve the type variables to avoid an ICE here.

Also, use the type-op machinery for implied outlives bounds.

e7e9f2e699 Remove IdxSet typedef and Rename {,Hybrid}IdxSetBuf as {,Hybrid}IdxSet. 
Now that the `Buf` vs. non-`Buf` distinction has been removed, it makes
sense to drop the `Buf` suffix and use the shorter names everywhere.
