abcfc3b762 Auto merge of #58065 - alexreg:refactor-smart_resolve_path_fragment, r=petrochenkov 
Factor out error reporting from `smart_resolve_path_fragment` fn

This function was ridiculously monolithic before. We now have three rather-less-monolithic-and-horrifying functions.

Deduplicate mismatched delimiter errors

Delay unmatched delimiter errors until after the parser has run to deduplicate them when parsing and attempt recovering intelligently.

Second attempt at #54029, follow up to #53949. Fix #31528.

4c9233cdeb Auto merge of #57885 - arielb1:xform-probe, r=nikomatsakis 
Avoid committing to autoderef in object method probing

This fixes the "leak" introduced in #57835 (see test for details, also apparently #54252 had no tests for the "leaks" that were fixed in it, so go ahead and add one).

Maybe beta-nominating because regression, but I'm against landing things on beta we don't have to.

impl iter_sources() and iter_chain() for dyn Error 
Examples:

```rust
let next_error_type_a = err
    .iter_chain()
    .filter_map(Error::downcast_ref::<ErrorTypeA>)
    .next();
```

```rust
let source_root_error = err.iter_chain().last();
```

d329d46a3f Auto merge of #58207 - nnethercote:intern_lazy_const, r=oli-obk 
Make `intern_lazy_const` actually intern its argument.

Currently it just unconditionally allocates it in the arena.

For a "Clean Check" build of the the `packed-simd` benchmark, this
change reduces both the `max-rss` and `faults` counts by 59%; it
slightly (~3%) increases the instruction counts but the `wall-time` is
unchanged.

For the same builds of a few other benchmarks, `max-rss` and `faults`
drop by 1--5%, but instruction counts and `wall-time` changes are in the
noise.

Fixes #57432, fixes #57829.

fix  #57593

This should not be merged without a crater run and maybe an FCP. Discussion is ongoing at  #57593.

312f3827fa Auto merge of #57184 - varkor:deny-warnings-lib, r=Mark-Simulacrum 
Deny warnings in libcore and libstd

This probably fixes https://github.com/rust-lang/rust/issues/57178 (though there may still be some crates that need warnings denied). At least after this change, rustc currently produces no warnings during compilation.

libcore, liballoc: disable tests in Miri

I am going to run the libcore and liballoc unit test suites in Miri.  Not all tests pass.  This PR disables a whole bunch of tests when running in Miri, to get us to a baseline from which I can investigate failures.

a2ec156a5b Auto merge of #58161 - davidtwco:issue-57960, r=arielb1 
Lower constant patterns with ascribed types.

Fixes #57960.

This PR fixes a bug introduced by #55937 which started checking user
type annotations for associated type patterns. Where lowering a
associated constant expression would previously return a
`PatternKind::Constant`, it now returns a `PatternKind::AscribeUserType`
with a `PatternKind::Constant` inside, this PR unwraps that to
access the constant pattern inside and behaves as before.
