Implements the first part of rust-lang/compiler-team#722, which moves functionality and use away from Diagnostic, onto DiagnosticBuilder.

Likely follow-ups:

  • Move things around, because this PR was written to minimize diff size, so some things end up in sub-optimal places. E.g. DiagnosticBuilder has impls in both diagnostic.rs and diagnostic_builder.rs.
  • Rename Diagnostic as DiagInner and DiagnosticBuilder as Diag.

Remove `diagnostic_builder.rs`

rust-lang#120576 moved a big chunk of `DiagnosticBuilder`'s functionality out of `diagnostic_builder.rs` into `diagnostic.rs`, which left `DiagnosticBuilder` spread across the two files.

This PR fixes that messiness by merging what remains of `diagnostic_builder.rs` into `diagnostic.rs`.

This is part of rust-lang/compiler-team#722.

I believe this has broken Rocket on nightly. Here's the ICE:

= help: message: invalid diagnostic level (Warning)

Rollup merge of rust-lang#121366 - nnethercote:rm-diagnostic_builder.rs, r=compiler-errors

Remove `diagnostic_builder.rs`

rust-lang#120576 moved a big chunk of `DiagnosticBuilder`'s functionality out of `diagnostic_builder.rs` into `diagnostic.rs`, which left `DiagnosticBuilder` spread across the two files.

This PR fixes that messiness by merging what remains of `diagnostic_builder.rs` into `diagnostic.rs`.

This is part of rust-lang/compiler-team#722.

`Rustc::emit_diagnostic` reconstructs a diagnostic passed in from the
macro machinery. Currently it uses the type `DiagnosticBuilder<'_,
ErrorGuaranteed>`, which is incorrect, because the diagnostic might be a
warning. And if it is a warning, because of the `ErrorGuaranteed` we end
up calling into `emit_producing_error_guaranteed` and the assertion
within that function (correctly) fails because the level is not an error
level.

The fix is simple: change the type to `DiagnosticBuilder<'_, ()>`. Using
`()` works no matter what the diagnostic level is, and we don't need an
`ErrorGuaranteed` here.

The panic was reported in rust-lang#120576.

I believe this has broken Rocket on nightly.

Thanks for the report, #121427 should fix it.

…ticBuilder, r=davidtwco

Overhaul `Diagnostic` and `DiagnosticBuilder`

Implements the first part of rust-lang/compiler-team#722, which moves functionality and use away from `Diagnostic`, onto `DiagnosticBuilder`.

Likely follow-ups:
- Move things around, because this PR was written to minimize diff size, so some things end up in sub-optimal places. E.g. `DiagnosticBuilder` has impls in both `diagnostic.rs` and `diagnostic_builder.rs`.
- Rename `Diagnostic` as `DiagInner` and `DiagnosticBuilder` as `Diag`.
