They will not be completely correct (one correcting .cfi_def_cfa_offset instruction on the beginning of the duplicated block would be missing), but hopefully this won't be a problem, because it is planned to reland Correct dwarf unwind information in function epilogue <https://reviews.llvm.org/D35844> right after this patch.
