The issue happens to more complicated test cases which I cannot reduce right now. Basically 8018d6be3459780e81a5da128a9915eb27909902 <https://reviews.llvm.org/rG8018d6be3459780e81a5da128a9915eb27909902> caused regressions in some PyTorch tests. Investigation shows the propagation of range metadata for bool type triggered some optimizations which caused some bool values to be loaded incorrectly. I will continue investigating the issue. However, I need a workaround for now.
