mark `min_exhaustive_patterns` as complete
This is step 1 and 2 of my [proposal](https://github.com/rust-lang/rust/issues/119612#issuecomment-1918097361) to move `min_exhaustive_patterns` forward. The vast majority of in-tree use cases of `exhaustive_patterns` are covered by `min_exhaustive_patterns`. There are a few cases that still require `exhaustive_patterns` in tests and they're all behind references.

Bump bootstrap compiler to just-built 1.77 beta
https://forge.rust-lang.org/release/process.html#master-bootstrap-update-t-2-day-tuesday
|

Invert diagnostic lints.
That is, change `diagnostic_outside_of_impl` and `untranslatable_diagnostic` from `allow` to `deny`, because more than half of the compiler has been converted to use translated diagnostics.
This commit removes more `deny` attributes than it adds `allow` attributes, which proves that this change is warranted.

This also takes care of other bootstrap-related changes.

Currently we always do this:
```
use rustc_fluent_macro::fluent_messages;
...
fluent_messages! { "./example.ftl" }
```
But there is no need, we can just do this everywhere:
```
rustc_fluent_macro::fluent_messages! { "./example.ftl" }
```
which is shorter.
|
|
The `fluent_messages!` macro produces uses of
`crate::{D,Subd}iagnosticMessage`, which means that every crate using
the macro must have this import:
```
use rustc_errors::{DiagnosticMessage, SubdiagnosticMessage};
```
This commit changes the macro to instead use
`rustc_errors::{D,Subd}iagnosticMessage`, which avoids the need for the
imports.

Aka trait_upcasting feature.
And also adjust the `deref_into_dyn_supertrait` lint.

Stabilize `result_option_inspect`
This PR stabilizes `result_option_inspect`:
```rust
// core::option
impl Option<T> {
pub fn inspect<F: FnOnce(&T)>(self, f: F) -> Self;
}
// core::result
impl Result<T, E> {
pub fn inspect<F: FnOnce(&T)>(self, f: F) -> Self;
pub fn inspect_err<F: FnOnce(&E)>(self, f: F) -> Self;
}
```

It lints against features that are inteded to be internal to the
compiler and standard library. Implements MCP #596.
We allow `internal_features` in the standard library and compiler as those
use many features and this _is_ the standard library from the "internal to the compiler and
standard library" after all.
Marking some features as internal wasn't exactly the most scientific approach, I just marked some
mostly obvious features. While there is a categorization in the macro,
it's not very well upheld (should probably be fixed in another PR).
We always pass `-Ainternal_features` in the testsuite
About 400 UI tests and several other tests use internal features.
Instead of throwing the attribute on each one, just always allow them.
There's nothing wrong with testing internal features^^

Fluent, with all the icu4x it brings in, takes quite some time to
compile. `fluent_messages!` is only needed in further downstream rustc
crates, but is blocking more upstream crates like `rustc_index`. By
splitting it out, we allow `rustc_macros` to be compiled earlier, which
speeds up `x check compiler` by about 5 seconds (and even more after the
needless dependency on `serde_json` is removed from
`rustc_data_structures`).

Tagged pointers, now with strict provenance!
This is a big refactor of tagged pointers in rustc, with three main goals:
1. Porting the code to the strict provenance
2. Cleanup the code
3. Document the code (and safety invariants) better
This PR has grown quite a bit (almost a complete rewrite at this point...), so I'm not sure what's the best way to review this, but reviewing commit-by-commit should be fine.

This allows us to get rid of the `rustc_const_eval->rustc_borrowck`
dependency edge which was delaying the compilation of borrowck.
The added utils in `rustc_middle` are small and should not affect
compile times there.

Move items not part of this stabilization to 'lazy_cell' or 'once_cell_try'
|
|
This makes it easier to open the messages file while developing on features.
The commit was the result of automatted changes:
for p in compiler/rustc_*; do mv $p/locales/en-US.ftl $p/messages.ftl; rmdir $p/locales; done
for p in compiler/rustc_*; do sed -i "s#\.\./locales/en-US.ftl#../messages.ftl#" $p/src/lib.rs; done

Instead of loading the Fluent resources for every crate in
`rustc_error_messages`, each crate generates typed identifiers for its
own diagnostics and creates a static which are pulled together in the
`rustc_driver` crate and provided to the diagnostic emitter.

Stabilize map_first_last
Stabilizes the following functions:
```Rust
impl<T> BTreeSet<T> {
pub fn first(&self) -> Option<&T> where T: Ord;
pub fn last(&self) -> Option<&T> where T: Ord;
pub fn pop_first(&mut self) -> Option<T> where T: Ord;
pub fn pop_last(&mut self) -> Option<T> where T: Ord;
}
impl<K, V> BTreeMap<K, V> {
pub fn first_key_value(&self) -> Option<(&K, &V)> where K: Ord;
pub fn last_key_value(&self) -> Option<(&K, &V)> where K: Ord;
pub fn first_entry(&mut self) -> Option<OccupiedEntry<'_, K, V>> where K: Ord;
pub fn last_entry(&mut self) -> Option<OccupiedEntry<'_, K, V>> where K: Ord;
pub fn pop_first(&mut self) -> Option<(K, V)> where K: Ord;
pub fn pop_last(&mut self) -> Option<(K, V)> where K: Ord;
}
```
Closes #62924
~~Blocked on the [FCP](https://github.com/rust-lang/rust/issues/62924#issuecomment-1179489929) finishing.~~ Edit: It finished!
