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.

Enable -mergefunc-use-aliases
If the Rust LLVM fork is used, enable the -mergefunc-use-aliases
flag, which will create aliases for merged functions, rather than
inserting a call from one to the other.
A number of codegen tests needed to be adjusted, because functions
that previously fell below the thunk limit are now being merged.
Merging is prevented in various ways now.
I expect that this is going to break something, somewhere, because
it isn't able to deal with aliases properly, but we won't find out
until we try :)
This fixes #52651.

Consider references and unions potentially inhabited during privacy-respecting inhabitedness checks
It isn't settled exactly how references to uninhabited types and unions of uninhabited types should act, but we should be more conservative here, as it's likely it will be permitted to soundly have values of such types.
This will also be more important in light of the changes at https://github.com/rust-lang/rust/pull/54125.

use MaybeUninit instead of mem::uninitialized for Windows Mutex
I hope this builds, I do not have a Windows machine to test...
|

name-anon-globals should always be run at the very end of the pass
pipeline, as optimization passes (in particular mergefunc) may
introduce new anonymous globals.
I believe we did not run into this earlier because it requires the
rather specific combination of a) mergefunc merging two weak functions
b) compilation not using thinlto.

arena: speed up TypedArena::clear and improve common patterns
- speed up `TypedArena::clear`: improves its performance by up to **33%** (in case of a single entry)
- simplify `DroplessArena::in_arena`

drop glue takes in mutable references, it should reflect that in its type
When drop glue begins, it should retag, like all functions taking references do. But to do that, it needs to take the reference at a proper type: `&mut T`, not `*mut T`.
Failing to retag can mean that the memory the reference points to remains frozen, and `EscapeToRaw` on a frozen location is a NOP, meaning later mutations cause a Stacked Borrows violation.
Cc @nikomatsakis @Gankro because Stacked Borrows
Cc @eddyb for the changes to miri argument passing (the intention is to allow passing `*mut [u8]` when `&mut [u8]` is expected and vice versa)

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.

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.

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.

Update books
This pulls in @Gankro 's final nomicon changes, and adds the edition guide as a submodule.
This is the final doc backport to beta for 1.31, as well.

Moved some feature gate tests to correct location
I evidently need to create some sort of GitHub monitor tool that yells at people when they do this in their PRs. ;-)

Fix panic with outlives in existential type
Don't panic in determining the privacy of a type if a lifetime outlives

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'.

Clean up and streamline the pretty-printer
Some minor improvements.
|
|
Reuse the `P` in `InvocationCollector::fold_{,opt_}expr`.
This requires adding a new method, `P::filter_map`.
This commit reduces instruction counts for various benchmarks by up to
0.7%.
|
|
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.

Assorted tweaks
- preallocate `VecDeque` in `Decodable::decode` (as it is done with other collections which can do it)
- add a FIXME to `String::from_utf16`

add test for issue #21335
Running this test with LLVM assertions enabled doesn't seem to trigger an assertion on my Mac.
Fixes #21335.

Use sort_by_cached_key when the key function is not trivial/free
I'm not 100% sure about `def_path_hash` (everything it does is inlined) but it seems like a good idea at least for the rest, as they are cloning.
