As of the stabilization of `std::backtrace` in Rust 1.65, this package flag has
no effect other than to enable an unused dependency on the `backtrace` crate.

Use `PostBorrowckAnalysis` in `check_coroutine_obligations`

This currently errors with:

```
error: concrete type differs from previous defining opaque type use
  --> tests/ui/coroutine/issue-52304.rs:10:21
   |
10 | pub fn example() -> impl Coroutine {
   |                     ^^^^^^^^^^^^^^ expected `{example::{closure#0} upvar_tys=() resume_ty=() yield_ty=&'{erased} i32 return_ty=() witness={example::{closure#0}}}`, got `{example::{closure#0} upvar_tys=() resume_ty=() yield_ty=&'static i32 return_ty=() witness={example::{closure#0}}}`
   |
   = note: previous use here
```

This is because we end up redefining the opaque in `check_coroutine_obligations` but with the `yield_ty = &'erased i32` from hir typeck, which causes the *equality* check for opaques to fail.

The coroutine obligtions in question (when `-Znext-solver` is enabled) are:

```
Binder { value: TraitPredicate(<Opaque(DefId(0:5 ~ issue_52304[4c6d]::example::{opaque#0}), []) as std::marker::Sized>, polarity:Positive), bound_vars: [] }

Binder { value: AliasRelate(Term::Ty(Alias(Opaque, AliasTy { args: [], def_id: DefId(0:5 ~ issue_52304[4c6d]::example::{opaque#0}), .. })), Equate, Term::Ty(Coroutine(DefId(0:6 ~ issue_52304[4c6d]::example::{closure#0}), [(), (), &'{erased} i32, (), CoroutineWitness(DefId(0:6 ~ issue_52304[4c6d]::example::{closure#0}), []), ()]))), bound_vars: [] }

Binder { value: AliasRelate(Term::Ty(Coroutine(DefId(0:6 ~ issue_52304[4c6d]::example::{closure#0}), [(), (), &'{erased} i32, (), CoroutineWitness(DefId(0:6 ~ issue_52304[4c6d]::example::{closure#0}), []), ()])), Subtype, Term::Ty(Alias(Opaque, AliasTy { args: [], def_id: DefId(0:5 ~ issue_52304[4c6d]::example::{opaque#0}), .. }))), bound_vars: [] }
```

Ignoring the fact that we end up stalling some really dumb obligations here (lol), I think it makes more sense for us to be using post borrowck analysis for this check anyways.

Don't enable anyhow's `backtrace` feature in opt-dist

As of the stabilization of `std::backtrace` in Rust 1.65, this package flag has no effect other than to enable an unused dependency on the `backtrace` crate.

(See <https://github.com/dtolnay/anyhow/blob/af0937ef72fbaf9784a6c991e029738728d025e2/Cargo.toml#L18-L23>.)

While the presence of this feature in opt-dist doesn't cause other tools (which use anyhow) to actually *build* backtrace, it does affect the global crate graph used for dependency version resolution. After removing this feature, we can use `cargo tree --invert --package backtrace` to see that the only remaining reverse-dependency of backtrace is `color-eyre`, which is used by `ui_test`.

@bors retry

Yielding priority to the stable release. Also, closing and opening kinda messed up bors:
