This would be helpful to find out optimizations that never trigger due to an error in their condition.
For example, it would have caught the bug that reopened https://bugs.webkit.org/show_bug.cgi?id=196325
Secondarily it would also help find which benchmark to focus on when trying to evaluate the impact of any of these optimizations.
