Rollup merge of #58346 - RalfJung:rpath-pop, r=Mark-Simulacrum
rpath computation: explain why we pop()

I was quite confused by this code until I got a debug log of what is going on.

Rollup merge of #58345 - RalfJung:2nd-filename, r=matthewjasper
When there are multiple filenames, print what got interpreted as filenames

I have written code that crafts command lines for rustc, and when I get "multiple input filenames provided" it can be quite hard to figure out where in this long list of arguments the mistake is hiding.  Probably I passed an argument to a flag that does not expect an argument, but which flag would that be?

This changes the error message to print the first two filenames, to make it easier to debug what is going on.

Rollup merge of #58332 - RalfJung:miri-copy-nonoverlapping, r=oli-obk
operand-to-place copies should never be overlapping

This seems to just work (verified with the Miri test suite).

std::sys::unix::stdio: explain why we do into_raw

I was quite puzzled why someone would call `into_raw` and then ignore the result.

Tiny expansion to docs for `core::convert`.

This is not really significant, accept or reject as you wish.  I just want to make sure I understand how the PR process works and that I'm doing it right before doing a bigger one for #33417.

Rollup merge of #57740 - JakubOnderka:ipv4addr-to_ne_bytes, r=scottmcm
Use `to_ne_bytes` for converting IPv4Addr to octets

It is easier and it should be also faster, because [`to_ne_bytes`](https://doc.rust-lang.org/std/primitive.u32.html#method.to_ne_bytes) just calls `mem::transmute`.

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:

```md

de111e6367 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 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.

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.

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.

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.

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.
