Revert <rust-lang#139998> because the original merge triggered download-rustc, which messes with test metrics and prevents us from properly comparing them before/after the change. The plan is to re-land this PR as-is, combined with a trivial compiler change to avoid download-rustc and get proper test metrics for comparison. This reverts commit be181dd, reversing changes made to 645d0ad.

Actually, let's not roll this up either in case it affects test diffs in a rollup (I don't expect that it does, but just in case). Giving this a higher priority to minimize number of merged PRs potentially affected (again, I don't expect differences but just to be extra safe). @bors rollup=never p=5 (revert to previous libtest executor) |

compiletest: Re-land using the new non-libtest executor by default This PR re-lands rust-lang#139998, which had the misfortune of triggering download-rustc in its CI jobs, so we didn't get proper test metrics for comparison with the old implementation. So that was PR was reverted in rust-lang#140233, with the intention of re-landing it alongside a dummy compiler change to inhibit download-rustc. --- Original PR description for rust-lang#139998: >The new executor was implemented in rust-lang#139660, but required a manual opt-in. This PR activates the new executor by default, but leaves the old libtest-based executor in place (temporarily) to make reverting easier if something unexpectedly goes horribly wrong. > >Currently the new executor can be explicitly disabled by passing the `-N` flag to compiletest (e.g. `./x test ui -- -N`), but eventually that flag will be removed, alongside the removal of the libtest dependency. The flag is mostly there to make manual comparative testing easier if something does go wrong. > >As before, there *should* be no user-visible difference between the old executor and the new executor. --- r? jieyouxu
