Unrolled build for rust-lang#128140

Rollup merge of rust-lang#128140 - veera-sivarajan:remove-ident-to-str-conversions, r=compiler-errors

Remove Unnecessary `.as_str()` Conversions

Because comparing interned values is much more efficient than converting a `rustc_span::symbol::Ident` to `&str`  and then doing the comparison.
