Thanks for the info!
Fixed max backedge count computation for loops with unknown stride by assuming a min stride of 1.

I can't find anything wrong with the IR. I am awaiting your response for more information.

Please ignore my previous email. My analysis was incorrect. The stride cannot be negative here as it will lead to UB.

Added more elaborate comments explaining why the change is correct.

Added bailout condition for predicated IVs.

- Added check to prove that the stride is truly unknown to ScalarEvolution so that the wrap flags are not propagated in edge cases.
- Removed unnecessary check for loopHasNoAbnormalExits() and loop entry guard.
- Fixed comments and the test.
