A few tests in llvm/test/Transforms/Util/PredicateInfo/ are using -reverse-iterate.
The option -reverse-iterate is enabled with +Asserts in usual cases, but it can be turned on/off regardless of LLVM_ENABLE_ASSERTIONS.
I wonder if this were incompatible to https://reviews.llvm.org/D33908 (r304757).
