Can't build Halide/LLVM (No space left on device)

[nathaniel-brough]

I've been trying to integrate the halide project, and I'm running into issues with github's action runners.

One of Halides dependencies is libllvm which I can't build and install with the base github action runners as I am getting the error no space left on device. I'm able to build this project locally on my machine just fine.

According the github action documentation there is "14 GB of SSD space" which is just shy of what I would need to build llvm on a linux machine. In fact some of the builds are successful (they don't run out of space).

I've run into similar limitations with the base github actions previously in #10174. Would it make sense to either;

1. Upgrade the github actions runners to the "large runners" with more space/ram OR
2. Configure the CI to use the same machines the OSS-fuzz actually builds with on a regular basis.

Not sure if this is relevant, but it may be possible to remove junk data, see for example #9836 ?

Ah yeah that pr looks great. It seems to help a little but it's still running out of space.

I don't know if we're going to do either of those solutions though they would make sense. It's a lot easier just to use github actions even if they don't work on some anomalous projects. You don't need to pass CI to integrate with oss-fuzz, especially if it's because our CI is broken.
