…pable Some optimization passes _improve_ compile times [1]. So we want to run some passes even with `-Copt-level=0`. That means that some of the lines in the test can be optimized away. To make regression testing more robust, we also want to run the test with such passes disabled. The solution is to use two revisions. One with default `-Copt-level=0` passes, and one "even less optimized", with enough optimization passes disabled to keep the maximum number of lines steppable. [1]: rust-lang/compiler-team#319

Avoid two of its uses in diagnostic reporting and effective visibility collection. The method is only supposed to be used inside the import resolution algorithm, and the removed uses happened after import resolution already converged. Some comments are also added.

Using `self.(non_)glob_decl` directly makes it more clear.

It is no longer needed to pass import validation, and the removal avoids some secondary errors. Also add a couple of asserts

Fixes rust-lang#154619. If `DerefPure` were dyn-compatible, a trait object of a subtrait of `DerefPure` could be created by unsize-coercing an existing type that implements `DerefPure`. But then the trait object could have its own non-pure impl of `Deref`/`DerefMut`, which is unsound, since the trait object would implement `DerefPure`. Thus, we make `DerefPure` dyn-incompatible.

…eature gate

…each other

…tput Add a flag to control verbose subprocess output for run-make tests. When using --no-capture on panic=abort test suites like cg_clif, passing test output can flood the terminal. This flag (default true) lets users opt out via --verbose-run-make-subprocess-output=false. Extract a private print_command_output helper in run-make-support to avoid inlining the output logic in handle_failed_output, ensuring failures always print regardless of the flag.

Seems stuck, lets wait another hour to see if it will rescue itself, and start a try job in parallel to see if it reproduces

For now assuming this was probably spurious, while also starting some try jobs on PRs in this rollup in case it's not
