Update UI tests which relied on old behavior of constructing a default error handler every time `early_warn` is called Skip `colored-session-opt-error.rs` on Windows hosts This is very cursed as to why it fails on Windows CI specifically: - The test emits a warning. - Warnings, and only warnings specifically, have a different 256-color between Windows and non-Windows hosts (other levels `set_intense(true)` unconditionally): https://github.com/rust-lang/rust/blob/e69c7306e2be08939d95f14229e3f96566fb206c/compiler/rustc_errors/src/lib.rs#L1792-L1794 Therefore, I added `// ignore-windows` test header to skip this test on Windows (it's sufficient to test color is enabled on at least one non-Windows host). 2023-06-28 17:32:31 +00:00			`// compile-flags: --error-format=human --cfg a{b}`
