Thanks for the change. I tried a few limits on the repro case I mentioned in D91722 <https://reviews.llvm.org/D91722>. It does look like 16 is a sweet spot at least for that case. :) Without forcing a limit, the case runs for 10+ hours..

| MaxDebugArgs | time  |
| 4            | 20.5s |
| 8            | 20.8s |
| 16           | 20.7s |
| 32           | 22.0s |
| 64           | 31.2s |
