Unrolled build for rust-lang#122293

Rollup merge of rust-lang#122293 - Enselic:no-bare-unix_sigpipe, r=fmease diagnostics: Do not suggest using `#[unix_sigpipe]` without a value Remove `Word` from the `unix_sigpipe` attribute template so that plain `#[unix_sigpipe]` is not included in suggestions of valid forms of the attribute. Also re-arrange diagnostics code slightly to avoid duplicate diagnostics. Tracking issue is rust-lang#97889.
