Bootstrap x86_64 musl by itself
It should slightly reduce build time and prepares ground for musl native tests.
NOTE: I haven't tested artifacts yet (only the build).
Can I have double try?

Add a tidy check for files with over 3,000 lines
Files with a large number of lines can cause issues in GitHub (e.g. https://github.com/rust-lang/rust/issues/60015) and also tend to be indicative of opportunities to refactor into less monolithic structures.
This adds a new check to tidy to warn against files that have more than 3,000 lines, as suggested in https://github.com/rust-lang/rust/issues/60015#issuecomment-483868594. (This number was chosen fairly arbitrarily as a reasonable indicator of size.) This check can be ignored with `// ignore-tidy-filelength`.
Existing files with greater than 3,000 lines currently ignore the check, but this helps us spot when files are getting too large. (We might try to split up all files larger than this in the future, as in https://github.com/rust-lang/rust/issues/60015).

Derive Default instead of new in applicable lint
Closes#60181
As far as I can see, at least within the `src/librustc_lint` directory this is the only place this is applicable.
Introduce hir::ExprKind::Use and employ in for loop desugaring.
In the `for $pat in $expr $block` desugaring we end with a `{ let _result = $match_expr; _result }` construct which makes `for` loops into a terminating scope and affects drop order. The construct was introduced in year 2015 by @pnkfelix in https://github.com/rust-lang/rust/pull/21984.
This PR replaces the construct with `hir::ExprKind::Use(P<hir::Expr>)` which is equivalent semantically but should hopefully be less costly in terms of compile time performance (to be determined).
This is extracted out of 91b0abdfb2 from https://github.com/rust-lang/rust/pull/59288 for easier review and so that the perf implications wrt. `for`-loops can be measured.

Add Pin::{into_inner,into_inner_unchecked}
These functions are useful for unsafe code that needs to temporarily pull smart pointers out of the `Pin`, e.g. [the change that inspired them](b4361780fa (diff-1a4e0ba4d1b539412ca576411ec6c7c2R258)) is taking a `Pin<Box<dyn Future>>`, turning it into a `*mut dyn Future` via `Box::into_raw(unsafe { Pin::into_inner_unchecked(pin) })` then later dropping this via `drop(Pin::from(Box::from_raw(ptr)))`. This can be accomplished today via `{ let ptr = unsafe { Pin::get_unchecked_mut(pin.as_mut()) } as *mut dyn Future; mem::forget(pin); ptr }`, but this is far more complicated and loses out on the symmetry of using `Box::into_raw` and `Box::from_raw`.
I'll extend the documentation on what guarantees `into_inner_unchecked` needs to uphold once I get some feedback on whether this API is wanted or not.

Fix index-page generation
Fixes#60096.
The minifier was minifying crates name in `searchIndex` key position, which was a bit problematic for multiple reasons.
r? @rust-lang/rustdoc
Set cfg(test) when rustdoc is running with --test option
Following a [discussion on twitter](https://twitter.com/burntsushi5/status/1117091914199785473), I proposed this change. What do you think about it?
r? @QuietMisdreavus

Improved error message when type must be bound due to generator.
Fixes#58930.
Keen to get some feedback - is this as minimal as we can get it or is there an existing visitor I could repurpose?
Implement saturating_abs() and saturating_neg() functions for signed integer types
Similar to wrapping_abs() / wrapping_neg() functions but saturating at the numeric bounds instead of wrapping around. Complements the existing set of functions with saturation mechanics.

Reexport IntErrorKind in std
Currently `IntErrorKind` can only be found in `core`. @Centril confirmed on Discord that this is unintentional (should I r? him in this situation?).
Should there be a test for this? As far as this *specific* situation goes, I don't think so, I'll risk it and say that there's no way this regresses. However, it might be a good idea to have some tool detect public items in `core` that are not reexported in `std`. Does this belong in tidy, or should that be a separate tool? Is there some rustc-specific *linter*? Unless that's entirely a dumb idea, this should probably get an issue.
Note: My local build hasn't finished yet, but it's well past the point where I would expect problems.
Fix#58270, fix off-by-one error in error diagnostics.
This fixes#58270 by checking if two diagnostics overlap completely when we're calculating the line offset for each message.
Add codegen test for PGO instrumentation.
This PR adds a codegen test that makes sure that LLVM actually generates instrumentation code when we enable PGO instrumentation in `rustc`.
The second commit updates a test case to the new commandline option syntax introduced in #59874. Without the fix the test still works, but it confusingly creates a directory called `test.profraw`, which usually is the name of the _file_ where profiling data is collected.
tweak unresolved label suggestion
Only suggest label names in the same hygiene context, and use a
structured suggestion.
Question for reviewer: Is this the right way to check for label hygiene?
