f107514aef Deal with EINTR in net timeout tests
We've seen sporadic QE failures in the timeout tests on this assertion:

    assert!(kind == ErrorKind::WouldBlock || kind == ErrorKind::TimedOut);

So there's an error, but not either of the expected kinds.  Adding a
format to show the kind revealed `ErrorKind::Interrupted` (`EINTR`).

For the cases that were using `read`, we can just use `read_exact` to
keep trying after interruption.  For those using `recv_from`, we have to
manually loop until we get a non-interrupted result.

8ee62bb239 ci: Only run compare-mode tests on one builder
The run-pass test suite currently takes 30 minutes on Windows, and
that appears to be roughly split between two 15 minute runs of the test
suite: one without NLL and one with NLL. In discussion on Discord the
platform coverage of the NLL compare mode may not necessarily be worth
it, so this commit removes the NLL compare mode from tests by default,
and then reenables it on only one builder.

Rollup merge of #56214 - scalexm:unification, r=nikomatsakis
Implement chalk unification routines

`ResolventOps` and `AggregateOps` are mostly straightforwardly translated from chalk. I had caught a few bugs already in my `chalk` branch and backported fixes to this branch, but there may be other ones left. EDIT: I hope there are none left now :)

Fixes #54935.

Rollup merge of #55011 - vi:panic_immediate_abort, r=alexcrichton
Add libstd Cargo feature "panic_immediate_abort"

It stop asserts and panics from libstd to automatically
include string output and formatting code.

Use case: developing static executables smaller than 50 kilobytes,
where usual formatting code is excessive while keeping debuggability
in debug mode.

May resolve #54981.

Rollup merge of #56360 - alexcrichton:linkchecker-omg, r=pietroalbini
Optimize local linkchecker program

I noticed on a [recent build][1] that the linkchecker stage of CI took a
whopping 15 minutes of CI time for something that should be near
instantaneous. Some local profiling showed some very hot functions and
clones which were pretty easy to remove, and now instead of running in
minutes locally it runs in seconds.

rustc 1.30.0's linker flavor inference is a non-backwards compat change to -Clinker

Part of #55396.

This commit modifies linker flavor inference to only remove the extension
to the linker when performing inference if that extension is a 'exe'.

Add TryFrom<&[T]> for [T; $N] where T: Copy

`TryFrom<&[T]> for &[T; $N]` (note *reference* to an array) already exists, but not needing to dereference makes type inference easier for example when using `u32::from_be_bytes`.

Also add doc examples doing just that.

d48ab693d1 Auto merge of #49219 - eddyb:proc-macro-decouple, r=alexcrichton
Decouple proc_macro from the rest of the compiler.

This PR removes all dependencies of `proc_macro` on compiler crates and allows multiple copies of `proc_macro`, built even by different compilers (but from the same source), to interoperate.

Practically, it allows:
* running proc macro tests at stage1 (I moved most from `-fulldeps` to the regular suites)
* using proc macros in the compiler itself (may require some rustbuild trickery)

On the server (i.e. compiler front-end) side:
* `server::*` traits are implemented to provide the concrete types and methods
  * the concrete types are completely separated from the `proc_macro` public API
  * the only use of the type implementing `Server` is to be passed to `Client::run`

On the client (i.e. proc macro) side (potentially using a different `proc_macro` instance!):
* `client::Client` wraps around client-side (expansion) function pointers
  * it encapsulates the `proc_macro` instance used by the client
  * its `run` method can be called by a server, to execute the client-side function
    * the client instance is bridged to the provided server, while it runs
    * ~~currently a thread is spawned, could use process isolation in the future~~
(not the case anymore, see #56058)
* proc macro crates get a generated `static` holding a `&[ProcMacro]`
  * this describes all derives/attr/bang proc macros, replacing the "registrar" function
  * each variant of `ProcMacro` contains an appropriately typed `Client<fn(...) -> ...>`

`proc_macro` public APIs call into the server via an internal "bridge":
* only a currently running proc macro `Client` can interact with those APIs
  * server code might not be able to (if it uses a different `proc_macro` instance)
    * however, it can always create and `run` its own `Client`, but that may be inefficient
* the `bridge` uses serialization, C ABI and integer handles to avoid Rust ABI instability
* each invocation of a proc macro results in disjoint integers in its `proc_macro` handles
  * this prevents using values of those types across invocations (if they even can be kept)
