Without the workaround applied, this test will produce malformed mappings that
cause `llvm-cov` to fail.
(And if it does emit well-formed mappings, they should be obviously incorrect.)
This method is trying to detect macro invocations, so that it can split a span
into two parts just after the `!` of the invocation.
Under some circumstances (probably involving nested macros), it gets confused
and produces a span that is larger than the original span, and possibly extends
outside its enclosing function and even into an adjacent file.
In extreme cases, that can result in malformed coverage mappings that cause
`llvm-cov` to fail. For now, we at least want to detect these egregious cases
and avoid them, so that coverage reports can still be produced.

Move `needless_pass_by_ref_mut`: `suspicious` -> `nursery`
[Related to [this Zulip thread](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/needless_pass_by_ref_mut.20isn't.20ready.20for.20stable)]
`needless_pass_by_ref_mut` has been released with some important bugs (notably having a lot of reported false positives and an ICE). So it may not be really ready for being in stable until these problems are solved. This PR changes the lint's category from `suspicious` to `nursery`, just that.

Fix: Write access check of `prefix` and `sysconfdir`
when DESTDIR is present.
Improvement: Instead of repeatedly reading `DESTDIR` within
each `fn prepare_dir` usage, read it once and pass it to
the `fn prepare_dir`.

Commit 8378487 from #114611 changed the location of an obligation
deduplication step in `opt_normalize_projection_type`. This meant that
deduplication stopped happening on one path where it was still
necessary, causing a couple of drastic performance regressions.
This commit moves the deduplication back to the old location. The good
news is that #114611 had four commits and 8378487 was of minimal
importance, so the perf benefits from that PR remain.
Fixes#116780, #116797.
(cherry picked from commit 91f2fbc867bfc31f2e103b09e605c61f1a450b33)
This should fix running tests on the emscripten target. In the future
it's expected we'll want to entirely remove this builder since it's a
tier 2 target, but for this initially beta-targeted patch keeping the
changes minimal is preferred.
Pass `-jN` from Make to `BOOTSTRAP_ARGS`
Enables the same functionality as `x -jN` in Make by passing the `-jN` arg from Make to the `BOOTSTRAP_ARGS` if it is specified.
Document that Instant may or may not include system-suspend time
Since people are still occasionally surprised by this let's make it more explicit. This doesn't add any new guarantees, only documents the status quo.
