This is a newly added triagebot capability, which allows registering and
then resolving concerns with an issue or a pull request. The concerns
are gathered by Triagebot in the issue/PR summary.
Concerns are different from notes: when a concern is resolved, it is
striked through in the issue/PR summary, and a link to the comment
resolving it is also added, whereas a note can only be removed and then
disappears from the summary.
The `has-concerns` label, which must be created at the time of merging
this change, will be automatically set on issues/PRs that have
unresolved concerns, and cleared when all concerns are resolved.

changelog: none
This tries to make progress on
https://github.com/rust-lang/rust/issues/78717 by using the ui_test
dependency handling instead of linking in the dependencies of clippy
itself with the tests. This partially reverts
https://github.com/rust-lang/rust-clippy/pull/11045. However, we still
use the old style of dealing with dependencies for clippy's own crates
and the "internal" tests, as otherwise those would get rebuilt which
takes too long.

Add new self-profiling event to cheaply aggregate query cache hit counts
Self-profile can record various types of things, some of them are not enabled, like query cache hits. Rustc currently records cache hits as "instant" measureme events, which records the thread ID, current timestamp, and constructs an individual event for each such cache hit. This is incredibly expensive, in a small hello world benchmark that just depends on serde, it makes compilation with nightly go from ~3s (with `-Zself-profile`) to ~15s (with `-Zself-profile -Zself-profile-events=default,query-cache-hit`).
We'd like to add query cache hits to rustc-perf (https://github.com/rust-lang/rustc-perf/pull/2168), but there we only need the actualy cache hit counts, not the timestamp/thread ID metadata associated with it.
This PR adds a new `query-cache-hit-count` event. Instead of generating individual instant events, it simply aggregates cache hit counts per *query invocation* (so a combination of a query and its arguments, if I understand it correctly) using an atomic counter. At the end of the compilation session, these counts are then dumped to the self-profile log using integer events (in a similar fashion as how we record artifact sizes). I suppose that we could dedup the query invocations in rustc directly, but I don't think it's really required. In local experiments with the hello world + serde case, the query invocation records generated ~30 KiB more data in the self-profile, which was ~10% increase in this case.
With this PR, the overhead of `-Zself-profile` seems to be the same as before, at least on my machine, so I also enabled query cache hit counts by default when self profiling is enabled.
We should also modify `analyzeme`, specifically [this](https://github.com/rust-lang/measureme/blob/master/analyzeme/src/analysis.rs#L139), and make it load the integer events with query cache hit counts. I can do that as a follow-up, it's not required to be done in sync with this PR, and it doesn't require changes in rustc.

This allows the use of `-Z track-diagnostics` to see the origin of
Clippy lints emission, as is already the case for lints coming from
rustc.

Currently we whether or not to build and test `f16` and `f128` support
mostly based on the target triple. This isn't always accurate, however,
since support also varies by backend and the backend version.
Since recently, `rustc` is aware of this with the unstable config option
`target_has_reliable_{f16,f128}`, which better represents when the types
are actually expected to be available and usable. Switch our
compiler-builtins and libm configuration to use this by probing `rustc`
for the target's settings.
A few small `cfg` fixes are needed with this.

`iter_directives`} for self-consistency
|
|
|
|
compiletest has confusingly two terminology to refer to the same concept
-- "headers" and "directives". To make this more self-consistent and
less confusing, stick with "directives" only.
This commit **intentionally** tries to be limited to move-only (modulo
some key usage reference renames) to help git history.
