Implement more detailed self profiling

Timing data and cache hits/misses are now recorded at the query level.
This allows us to show detailed per query information such as total time
for each query.

To see detailed query information in the summary pass the `-Z verbose`
flag. For example:

```
rustc -Z self-profile -Z verbose hello_world.rs
```

results in something like:

Fixes #54141

Auto merge of #58103 - RalfJung:mir-shim-dump, r=eddyb

Make -Zdump-mir dump shims

Fixes https://github.com/rust-lang/rust/issues/53532 by (a) making the MIR shim generation use the MIR pass infrastructure, and (b) fixing said infrastructure to handle the fallout.

Add EmbeddedBook to test list in bootstrap

Auto merge of #57770 - Zoxc:no-hash-query, r=michaelwoerister

Add a query type which is always marked as red if it runs

This is useful for queries which produce results which are very likely to change if their inputs do.

I also expect this to be useful for end to end queries because 1) we don't need `HashStable` impls and 2) we avoid the overhead of hashing the result of large results like the AST or the HIR map.

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.

r? @centril

Auto merge of #57944 - estebank:unclosed-delim-the-quickening, r=oli-obk

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.

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.

r? @nikomatsakis

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();
```

librustc_codegen_ssa => 2018

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.

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.

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.

Add embedded book to test such that checktools works

r? @alexcrichton

FWIW this doesn't attempt to make sure we don't break check tools again -- we intentionally make the bash script not exit when x.py fails so we'd need some special case handling so for now I'm just fixing the bug itself, not its cause.
