🤖 LLM disclosure: I probably should have tested this change manually, though I let LLM verify it working, sorry. Will do a manual test when I have time or if somebody beats me on that.

⚠️ Warning ⚠️

• Some commits in this PR modify submodules.

  If this was not intentional, see I changed a submodule on accident in the rustc dev guide.

[Urgau]

I tested the GDB and LLDB changes locally, looks good to me.

r=me on that part

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
