653463731a Auto merge of #95563 - dingxiangfei2009:dxf-rfc66-refactor, r=nikomatsakis 
Move the extended lifetime resolution into typeck context

Related to #15023

This PR is based on the [idea](https://github.com/rust-lang/rust/issues/15023#issuecomment-1070931433) of #15023 by `@nikomatsakis.`

This PR specifically proposes to
- Delay the resolution of scopes of rvalues to a later stage, so that enough type information is available to refine those scopes based on relationships of lifetimes.
- Highlight relevant parts that would help future reviews on the next installments of works to fully implement a solution to RFC 66.

acfd327fd4 Auto merge of #97177 - oli-obk:const-stability, r=davidtwco 
Implement proper stability check for const impl Trait, fall back to unstable const when undeclared

Continuation of #93960

`@jhpratt` it looks to me like the test was simply not testing for the failure you were looking for? Your checks actually do the right thing for const traits?

5ff331142e Move check to existing pass 
This alters the diagnostics a bit, as the trait method is still stable.
The only thing this check does is ensure that compilation fails if a
trait implementation is declared const-stable.

f0620c9503 Proper const stability check, default to unstable 
Rather than deferring to const eval for checking if a trait is const, we
now check up-front. This allows the error to be emitted earlier, notably
at the same time as other stability checks.

Also included in this commit is a change of the default const stability
level to UNstable. Previously, an item that was `const` but did not
explicitly state it was unstable was implicitly stable.

a9dd4cfa6b Add and use stability helper methods 
This avoids an ambiguity (when reading) where `.level.is_stable()` is
not immediately clear whether it is general stability or const
stability.
