illumos' `ld` does not support a flag like either SHF_GNU_RETAIN or
SHF_SUNW_NODISCARD, so there is no way to communicate `#[used(linker)]`
for that target. Setting `USED_LINKER` to try results in LLVM setting
SHF_SUNW_NODISCARD for Solaris-like targets, which is an unknown section
header flag for illumos `ld` and prevents sections from being merged
that otherwise would.
As a motivating example, the `inventory` crate produces
`#[used]` items to merge into `.init_array`. Because those items have an
unknown section header flag they are not merged with the default
`.init_array` with `frame_dummy`, and end up never executed.
Downgrading `#[used]` to `#[used(compiler)]` on illumos keeps
so-attributed items as preserved as they had been before
https://github.com/rust-lang/rust/pull/140872. As was the case before
that change, because rustc passes `-z ignore` to illumos `ld`, it's
possible that `used` sections are GC'd at link time.
https://github.com/rust-lang/rust/issues/146169 describes this
unfortunate circumstance.

port `#[debugger_visualizer]` to the new attribute system
|
|
Add an attribute to check the number of lanes in a SIMD vector after monomorphization
Allows std::simd to drop the `LaneCount<N>: SupportedLaneCount` trait and maintain good error messages.
Also, extends rust-lang/rust#145967 by including spans in layout errors for all ADTs.

This uses the feature gate for
https://github.com/rust-lang/rust/issues/143352, but is described in
https://github.com/rust-lang/rfcs/pull/3820 which is strongly tied to
the experiment.

`rustc_errors` depends on numerous crates, solely to implement its
`IntoDiagArg` trait on types from those crates. Many crates depend on
`rustc_errors`, and it's on the critical path.
We can't swap things around to make all of those crates depend on
`rustc_errors` instead, because `rustc_errors` would end up in
dependency cycles.
Instead, move `IntoDiagArg` into `rustc_error_messages`, which has far
fewer dependencies, and then have most of these crates depend on
`rustc_error_messages`.
This allows `rustc_errors` to drop dependencies on several crates,
including the large `rustc_target`.
(This doesn't fully reduce dependency chains yet, as `rustc_errors`
still depends on `rustc_hir` which depends on `rustc_target`. That will
get fixed in a subsequent commit.)

Disabling loading of pretty printers in the debugger itself is more
reliable. Before this commit the .gdb_debug_scripts section couldn't be
included in dylibs or rlibs as otherwise there is no way to disable the
section anymore without recompiling the entire standard library.
