Auto merge of rust-lang#128913 - saethlin:unignore-debuginfo-tests, r…

…=<try> Enable debuginfo tests that were "temporarily disabled" for the past 6 years `tests/debuginfo/drop-locations.rs` No idea why we are setting `-O -Cno-prepopulate-passes`. Nowadays that turns on MIR opts, no idea what it did in 2018. Turning off optimizations makes just loc2 missing. That seems like a bug in debuginfo generation. Turning off all MIR opts and even adding a `drop(s)` on that line doesn't help. Cursed. Keeping this test ignored. `tests/debuginfo/option-like-enum.rs` Debuggers are better at Rust! Also one inexplicable change. No idea why we used to expect that. Deleted. `tests/debuginfo/function-arg-initialization.rs` SingleUseConsts produces incoherent gdb behavior. Seems like a bug. `tests/debuginfo/macro-stepping.rs` Also broken by SingleUseConsts. I hate tests like this, nobody uses a debugger on code that's just assigning consts to unused variables. Test should be rewritten with realistic code. `tests/debuginfo/basic-types-metadata.rs` Debuggers are better at Rust! Diverging functions don't have -> ! in their whatis output anymore? Not sure if that is a bug. try-job: test-various try-job: aarch64-apple try-job: x86_64-msvc try-job: x86_64-mingw try-job: i686-msvc try-job: i686-mingw try-job: armhf-gnu try-job: dist-various-1 try-job: aarch64-gnu
