Rollup merge of #110299 - kylematsuda:earlybinder-impl-subject, r=compiler-errors
Switch to `EarlyBinder` for `impl_subject` query

Part of the work to finish https://github.com/rust-lang/rust/issues/105779.

Several queries `X` have a `bound_X` variant that wraps the output in `EarlyBinder`. This adds `EarlyBinder` to the return type of the `impl_subject` query and removes `bound_impl_subject`.

Rollup merge of #110298 - jmaargh:jmaargh/hypot-docs-edge-cases, r=thomcc
Cover edge cases for {f32, f64}.hypot() docs

Fixes #88944

The Euclidean distance is a more general way to express what these functions do, and covers the edge cases of zero and negative inputs.

Does not cover the case of non-normal input values (as the [POSIX docs](https://pubs.opengroup.org/onlinepubs/9699919799.2008edition/) do), but the docs for the rest of the functions in these modules do not address this, I assumed it was not desired.

Rollup merge of #110279 - GuillaumeGomez:compiler-macro-derive, r=notriddle
rustdoc: Correctly handle built-in compiler proc-macros as proc-macro and not macro

Part of https://github.com/rust-lang/rust/issues/110111.

There were actually one issue split in two parts:
 * Compiler built-in proc-macro were incorrectly considered as macros and not proc-macros.
 * Re-exports of compiler built-in proc-macros were considering them as macros.

Both issues can be fixed by looking at the `MacroKind` variant instead of just relying on information extracted later on.

Rollup merge of #110180 - lcnr:canonicalize, r=compiler-errors
don't uniquify regions when canonicalizing

uniquifying causes a bunch of issues, most notably it causes `AliasEq(<?x as Trait<'a>>::Assoc, <?x as Trait<'a>>::Assoc)` to result in ambiguity because both `normalizes-to` paths result in ambiguity and substs equate should trivially succeed but doesn't because we uniquified `'a` to two different regions.

I originally added uniquification to make it easier to deal with requirement 6 from the dev-guide: https://rustc-dev-guide.rust-lang.org/solve/trait-solving.html#requirements

> ### 6. Trait solving must be (free) lifetime agnostic
>
> Trait solving during codegen should have the same result as during typeck. As we erase
> all free regions during codegen we must not rely on them during typeck. A noteworthy example
> is special behavior for `'static`.

cc https://github.com/rust-lang/rustc-dev-guide/pull/1671

Relying on regions being identical may cause ICE during MIR typeck, but even without this PR we can end up relying on that as type inference vars can resolve to types which contain an identical region. Let's land this and deal with any ICE that crop up as we go. Will look at this issue again before stabilization.

Rollup merge of #110158 - TDecking:obsolete_test, r=ChrisDenton
Remove obsolete test case

This test case was supposed to cover issue #31109 at some point.
It never did anything, as the issue was still open at the time of its creation.
When the issue was resolved, the `issue31109` test case was created,
making the existence of this test pointless.

Rollup merge of #109225 - seanlinsley:patch-1, r=ChrisDenton
Clarify that RUST_MIN_STACK may be internally cached

For larger applications it's important that users set `RUST_MIN_STACK` at the start of their program because [`min_stack`](7d3e03666a/library/std/src/sys_common/thread.rs) caches the value. Not doing so can lead to their `env::set_var` call surprisingly not having any effect.

In my own testing `RUST_MIN_STACK` had no effect until I moved it to the top of `main()`. Hopefully this clarification in the docs will help others going forward.

Move most ui-fulldeps tests to ui/

Same rationale as https://github.com/rust-lang/rust/pull/109770, they don't actually need a stage 2 build.

This increases the limit for the UI directory because otherwise it was annoying to be constantly moving files into subdirectories when I fixed a test; https://github.com/rust-lang/rust/pull/109873 makes up for it.

88ee6e5a6c Fix tests on wasm
The `std` test straightforwardly can't work without file descriptors;
 #99417 tracks moving it out of tests/ui.

`issue-13560.rs` requires the target to support dynamic linking.

`extern-mod-syntax` is interesting. The original test was added to check
if `extern mod` could be parsed correctly and used `extern mod std` and
an import:
138dc3048a (diff-73700e1e851b7a37bc92174635dab726124c82e5bfabbbc45b4a3c2e8e14fadd)
At some point `std::json::Object` was moved out of std to an unstable
rustc-only `extras` crate, and rather than just changing the import it
got changed to use the unstable crate. When `extras` was removed, people
assumed the test was meant to also test rustc_private and changed it to
another unstable crate rather than using something in std.

This changes the test to remove the `rustc_private` import, to allow it
to work properly when cross-compiling.

marked `ignore-stage1` have been keep in fulldeps.

resolve: Pre-compute non-reexport module children

Instead of repeating the same logic by walking HIR during metadata encoding.

The only difference is that we are no longer encoding `macro_rules` items, but we never currently need them as a part of this list. They can be encoded separately if this need ever arises.

`module_reexports` is also un-querified, because I don't see any reasons to make it a query, only overhead.

Added diagnostic for pin! macro in addition to Box::pin if Unpin isn't implemented

I made a PR earlier, but accidentally renamed a branch and that deleted the PR... sorry for the duplicate

Currently, if an operation on `Pin<T>` is performed that requires `T` to implement `Unpin`, the diagnostic suggestion is to use `Box::pin` ("note: consider using `Box::pin`").

This PR suggests pin! as well, as that's another valid way of pinning a value, and avoids a heap allocation. Appropriate diagnostic suggestions were included to highlight the difference in semantics (local pinning for pin! vs non-local for Box::pin).

Fix diff option conflict in UI test

Trivial fix for test case `tests/run-make/rustdoc-verify-output-files`,
it's failing on MacOS, the `-u` option specifies the unified context format, while the `-q` option specifies only brief output. These two options are incompatible, since the unified context format produces a more detailed output than the brief output format.
