I'm not aware of any such setup unfortunately...

But I use a custom github actions setup for test running various things on the public github actions runners - see https://github.com/mstorsjo/llvm-project/commit/gha-mingw-compiler-rt. I pushed a combination of that with this test branch, which should produce results at https://github.com/mstorsjo/llvm-project/actions/runs/14078778580.

It should probably be possible to do a similar setup with clang-cl as well; it's mainly a question if it can be built with a recent enough separate build of clang (so one can build just compiler-rt), or if it requires a full build of clang+compiler-rt at the same time (which takes a fair bit of time on the github actions runners).
