This update makes sure that `flang-new -O2 -O0` will run at `-O0` rather than `-O2`. This bug was identified and originally fixed by Vyacheslav Zakharin in https://reviews.llvm.org/D130035. I've extracted the fix into a separate patch. co-authored by: Vyacheslav Zakharin <vyacheslav.p.zakharin@intel.com> Differential Revision: https://reviews.llvm.org/D130104
