tests/codegen: use -Copt-level=3 instead of -O 2025-02-08 19:45:40 -08:00			`//@ compile-flags: -Copt-level=3`

Run rustfmt on `tests/codegen/`. Except for `simd-intrinsic/`, which has a lot of files containing multiple types like `u8x64` which really are better when hand-formatted. There is a surprising amount of two-space indenting in this directory. Non-trivial changes: - `rustfmt::skip` needed in `debug-column.rs` to preserve meaning of the test. - `rustfmt::skip` used in a few places where hand-formatting read more nicely: `enum/enum-match.rs` - Line number adjustments needed for the expected output of `debug-column.rs` and `coroutine-debug.rs`. 2024-05-29 14:11:20 +10:00			`#![crate_type = "rlib"]`
