…ng pass counts in large projects
This is useful for bisecting passes in large projects:
1. create a config file from a full build log. E.g. with
```
grep -e '-module-name' build.log | sed -e 's/.*-module-name \([^ ]*\) .*/\1:10000000/' | sort | uniq > config.txt
```
2. add the `-Xllvm -sil-pass-count-config-file config.txt` option to the project settings
3. bisect by modifying the counts in the config file
4. clean-rebuild after each bisecting step
