Benchmarking is taking a while for me, and I can only really run benchmarks with low run-time variance overnight. I will post more over time as I get more benchmark projects added. 

Here is the result from benchmarking one C project, libsodium, so far. These results are for 13 runs after some warmup runs. This is with a debug build and default checkers enabled using CodeChecker:

base/main branch of clang:
- Mean: 681.3 seconds
- Stdev: 12.8 seconds

This branch:
- Mean: 678.1 seconds
- Stdev 15.4 seconds
