4fb57e0796 one-time diagnostic and suggestion for reëxporting private variant error 
We issue just one message for an erroneous glob private variant reëxport
(using the Session's one-time-diagnostics capability), but individual
(non-glob) such erroneous reëxports still get their own messages. The
suggestion to make the enum public is also one-time.

The enum variant reëxport error didn't have an associated error code
(and remedying this here is deemed out of the scope of this commit), so
we resort to the expediency of using 0 as the `DiagnosticMessageId`
value.

Adding Debug to NameResolution was helpful in development.

This resolves #46209.

883f5e5e65 one-time diagnostics: span_suggestion, generalize methods for non-lints 
304c8b1eda made the Session's one-time-diagnostics set take a
special-purpose `DiagnosticMessageId` enum rather than a LintID so that
it could support more than just lints, but the `diag_span_note_once` and
`diag_note_once` methods continued to take references to lints: for API
consistency, we now make these methods take a `DiagnosticMessageId`
while we add support for one-time span-suggestions.

c7b6d8263b Auto merge of #45837 - SimonSapin:file_read_write, r=dtolnay 
Add read, read_string, and write functions to std::fs

New APIs in `std::fs`:

```rust
pub fn read<P: AsRef<Path>>(path: P) -> io::Result<Vec<u8>> { … }
pub fn read_string<P: AsRef<Path>>(path: P) -> io::Result<String> { … }
pub fn write<P: AsRef<Path>, C: AsRef<[u8]>>(path: P, contents: C) -> io::Result<()> { ... }
```

(`read_string` is based on `read_to_string` and so returns an error on non-UTF-8 content.)

Before:

```rust
use std::fs::File;
use std::io::Read;

let mut bytes = Vec::new();
File::open(filename)?.read_to_end(&mut bytes)?;
do_something_with(bytes)
```

After:

```rust
use std::fs;

do_something_with(fs::read(filename)?)
```

88fc3bc271 Auto merge of #46556 - michaelwoerister:enable-query-caching, r=nmatsakis 
incr.comp.: Enable query result caching for many more queries

Newly cached queries are:
* const_is_rvalue_promotable_to_static
* trans_fulfill_obligation
* optimized_mir
* unsafety_check_result
* borrowck
* mir_borrowck
* mir_const_qualif
* contains_extern_indicator
* def_symbol_name
* symbol_name

This also includes the stricter `Span` hashing first mentioned in #46490, which will lead to more false positives in release builds but overall is more correct -- and necessary for caching MIR. Hopefully we will soon be able to reduce the rate of false positives again by factoring `Span` out of MIR.

rustc: Further tweak linkage in ThinLTO

In #46382 the logic around linkage preservation with ThinLTO ws tweaked but the
loop that registered all otherwise exported GUID values as "don't internalize
me please" was erroneously too conservative and only asking "external" linkage
items to not be internalized. Instead we actually want the inversion of that
condition, everything *without* "local" linkage to be internalized.

This commit updates the condition there, adds a test, and...

Closes #46543

655303ce9b Rollup merge of #46539 - oli-obk:cargo_lock, r=alexcrichton 
Do not automatically merge `Cargo.lock`

It essentially never does what it's supposed to and often leaves the `Cargo.lock` in a state where it needs manual adjustments or resetting to master/yourbranch. With this setting git will always choose your `Cargo.lock` over the one from master and report a merge error (if both master and your branch touched `Cargo.lock`). Now you can run `./x.py help` and it should normally update the `Cargo.lock` to be one that has everything needed by master and your branch.
