- improve messaging and add instructions how to fix the patch
- fix application of patch stack. Now base commit and order of patches
should be correct
- set origin to llvm-project fork to avoid accidental operations on origin
- use annotations to make issues visible
- create commits with original author of change
- add patches we tried to apply to artifacts
- patching / commits works locally if --push-branch=false is set
- misc renames / wordings
