check `stage0`, `channel` and `version` files for CI rustc

2024-10-14T17:23:58+00:00

These files have important role for compiler builds, so include them in the "if-unchanged" rustc logic. Signed-off-by: onur-ozkan (cherry picked from commit 6e6cbdd2df0ae5a025c458d95a4c84df1b6af092)

stabilize `ci_rustc_if_unchanged_logic` test Makes `ci_rustc_if_unchanged_logic` test more stable and re-enables it. Previously, it was expecting CI-rustc to be used all the time when there were no changes, which wasn’t always the case. Purpose of this test is making sure we don't use CI-rustc while there are changes in compiler and/or library, but we don't really need to cover cases where CI-rustc is not enabled. Second commit was pushed for making a change in the compiler tree, so `ci_rustc_if_unchanged_logic` can be tested properly in merge CI.

Rollup merge of #131442 - jieyouxu:mir-opt-rebuild, r=onur-ozkan

Match std `RUSTFLAGS` for host and target for `mir-opt` test suite to fix double std build/rebuilds Previously the bootstrap compiletest `Step::run` flow had: ```rs // ensure that `libproc_macro` is available on the host. builder.ensure(compile::Std::new(compiler, compiler.host)); // ... if suite == "mir-opt" { builder.ensure(compile::Std::new_for_mir_opt_tests(compiler, target)); } else { builder.ensure(compile::Std::new(compiler, target)); } ``` This can cause unnecessary std rebuilds (even on the same invocation) because if host == target then `builder.ensure(compile::Std::new_for_mir_opt_tests(compiler, target))` will have different `RUSTFLAGS` than `builder.ensure(compile::Std::new(compiler, compiler.host))`. This PR fixes that by matching up std `RUSTFLAGS` if the test suite is `mir-opt`: ```rs if suite == "mir-opt" { builder.ensure(compile::Std::new_for_mir_opt_tests(compiler, compiler.host)); } else { builder.ensure(compile::Std::new(compiler, compiler.host)); } ``` This is a short-term fix, the better fix is to enforce how `RUSTFLAGS` are handled as described in https://github.com/rust-lang/rust/issues/131437#issuecomment-2401710727. Fixes #131437.
