<!--LLVM PR SUMMARY COMMENT-->
@llvm/pr-subscribers-github-workflow
Author: Tom Stellard (tstellar)
<details>
<summary>Changes</summary>
This reuses most of the generate-buildkite-pipeline-premerge script which determines which projects to build and which check targets to use. The workflow file is also based on the linux workflow from PR#<!-- -->80951.
Unlike buildkite, which tested everything, this new workflow only tests clang, llvm, and lld due to resource constraints on the GitHub runners.
