It was previously cached for modules loaded from `fn get_module`, but not for modules loaded from `fn build_reduced_graph_for_external_crate_res`.
This also makes all foreign modules use their real parent, span and expansion instead of possibly a parent/span/expansion of their reexport.
An ICE happening on attempt to decode expansions for foreign enums and traits is avoided.
Also local enums and traits are now added to the module map.
Avoid nondeterminism in trimmed_def_paths
Previously this query depended on the global interning order of Symbols, which
meant that irrelevant changes could influence the query and cause
recompilations. This commit ensures that the return set is stable and will not
be affected by the global order by deterministically (in lexicographic order)
choosing a name to use if there are multiple names for a single DefId.
This should fix the cause of the [regressions] in #83343.
[regressions]: https://perf.rust-lang.org/compare.html?start=9620f3a84b079decfdc2e557be007580b097fe43&end=addb4da686a97da46159f0123cb6cdc2ce3d7fdb
Fix clippy lints
I'm currently working on allowing clippy to run on librustdoc after a discussion I had with `@Mark-Simulacrum.` So in the meantime, I fixed a few lints on the compiler crates.
For `self == Self::MIN && rhs == -1`, LLVM does not realize that this is the
same check made by `self / rhs`, so the code generated may have some unnecessary
duplication. For `(self == Self::MIN) & (rhs == -1)`, LLVM realizes it is the
same check.
The checks removed here caused a small perf regression:
https://github.com/rust-lang/rust/pull/88824#issuecomment-932664761
Since the attribute is currently only applied to traits, I don't think
it's worth keeping the additional checks for now.
If/when we decide to apply the attribute somewhere else, we can
(partially) revert this and evaluate if the perf impact is acceptable.
A subset of places referred to 'super-trait', so this changes them
to all use 'supertrait'. This matches 'supertype' and some other
usages. An exception is 'auto-trait' which is consistently used
in that manner.

Normalize after substituting via `field.ty()`
Back in https://github.com/rust-lang/rust/issues/72476 I hadn't understood where the problem was coming from, and only worked around the issue. What happens is that calling `field.ty()` on a field of a generic struct substitutes the appropriate generics but doesn't normalize the resulting type.
As a consumer of types I'm surprised that one would substitute without normalizing, feels like a footgun, so I added a comment.
Fixes https://github.com/rust-lang/rust/issues/89393.
Clarify a sentence in the documentation of Vec (#84488)
I literally changed a single word, but this should clear up the confusion of #84488. Can probably be `rollup`ed :) (My first PR, hope I'm doing this right)

Replace whitespaces in doctests' name with dashes
Fixes#88263.
Instead of handling white spaces when we filter tests (which would be quite complicated since we split on them!), I propose to instead replace them with dashes.
So for example, this:
```console
test foo.rs - Iter2<T, P>::len (line 13) ... ok
test foo.rs - Iter<T, P>::len (line 4) ... ok
```
becomes:
```console
test foo.rs - Iter<T,-P>::len (line 4) ... ok
test foo.rs - Iter2<T,-P>::len (line 13) ... ok
```

Fix use after drop in self-profile with llvm events
self-profile with `-Z self-profile-events=llvm` have failed with a segmentation fault due to this use after drop.
this type of events can be more useful now that the new passmanager is the default.
Coerce const FnDefs to implement const Fn traits
You can now pass a FnDef to a function expecting `F` where `F: ~const FnTrait`.

platform-support.md: correct ARMv7+MUSL platform triple notes
This PR fixes two minor inconsistencies in the platform support list.
- use "with MUSL" suffix for "armv7-unknown-linux-musleabi"
- add "hardfloat" suffix for "armv7-unknown-linux-musleabihf"

rustdoc: Clarified the attribute which prompts the warning
The example call was lacking clarification of the `#![warn(rustdoc::invalid_codeblock_attributes)]` attribute which generates the specified warning.
Rework HIR API to make invocations of the hir_crate query harder.
`hir_crate` forces the recomputation of queries that depend on it.
This PR aims at avoiding useless invocations of `hir_crate` by making dependent code go through `tcx.hir()`.
