0b664d91 - [FixIrreducible] Handle conditional branch with both successors as header (#206057)

[FixIrreducible] Handle conditional branch with both successors as header (#206057) A conditional branch redirecting edges to the cycle header may have both successors equal to the header (e.g. `br i1 %c, label %h, label %h`), which the previous `Succ1 = Succ0 ? nullptr : Header` logic mishandled by dropping the second edge. Check each successor independently against the header instead. Fixes https://github.com/llvm/llvm-project/issues/191979.
