Subject: [PATCH 1/2] workflows: Merge LLVM tests together into a single job

This is possible now that the free GitHub runners for Windows and Linux
have more disk space:
https://github.blog/2024-01-17-github-hosted-runners-double-the-power-for-open-source/

I also had to switch from macOS-11 to macOS-13 in order to prevent the
job from timing out.  macOS-13 runners have 4 vCPUs and the macOS-11
runners only have 3.
