When these methods were originally written, I wasn't aware that
`newtype_index!` already supports addition with ordinary numbers, without
needing to unwrap and re-wrap.
If a BCB has more than one code region, those extra regions can now all be
stored in the same coverage statement, instead of being stored in additional
statements.
The concrete type `CoverageSpan` is no longer used outside of the `spans`
module.
This is a separate patch to avoid noise in the preceding patch that actually
encapsulates coverage spans.
By encapsulating the coverage spans in a struct, we can change the internal
representation without disturbing existing call sites. This will be useful for
grouping coverage spans by BCB.
This patch includes some changes that were originally in #115912, which avoid
the need for a particular test to deal with coverage spans at all.
(Comments/logs referring to `CoverageSpan` are updated in a subsequent patch.)
std_instead_of_core: avoid lint inside of proc-macro
- fixes https://github.com/rust-lang/rust-clippy/issues/10198
note: The lint for the reported `thiserror::Error` has been suppressed by [Don't lint unstable moves in std_instead_of_core](https://github.com/rust-lang/rust-clippy/pull/9545/files#diff-2cb8a24429cf9d9898de901450d640115503a10454d692dddc6a073a299fbb7eR29) because `thiserror::Error` internally implements `std::error::Error for (derived struct)`.
changelog: [`std_intead_of_core`]: avoid linting inside proc-macro
I confirmed this change fixes the problem:

We're stabilizing `async fn` in trait (AFIT), but we have some
reservations about how people might use this in the definitions of
publicly-visible traits, so we're going to lint about that.
This is a bit of an odd lint for `rustc`. We normally don't lint just
to have people confirm that they understand how Rust works. But in
this one exceptional case, this seems like the right thing to do as
compared to the other plausible alternatives.
In this commit, we describe the nature of this odd lint.
Add missing #[inline] on AsFd impl for sys::unix::fs::File
This operation should be extremely cheap, at most the `mov` of the underlying file descriptor, but due to this missing `#[inline]` it is currently a function call.
Print GHA log groups to stdout instead of stderr
In all other places (e.g. `bootstrap.py`, `opt-dist`), we use stdout instead of stderr. I think that using stderr might be causing some discrepancies in the log, where sometimes the contents of a group "leak" outside the group. Let's see what happens if we use stdout instead. It's possible that it will be worse, since we print most stuff to stderr (?).
