- Make sure we keep -DNDEBUG. At some point %{optflags} must have

lost it, perhaps because CMake usually adds it on top. So when
  overriding CMAKE_{C,CXX}_FLAGS_RELWITHDEBINFO, we make sure to
  take over the other flags. We drop LLVM_ENABLE_ASSERTIONS=OFF,
  because that's the default anyway and hasn't helped here.
- Add llvm-scev-fix-isImpliedViaMerge.patch: fixes a miscompilation
  caused by mixing up values of the current and previous iteration.
  (See gh#llvm/llvm-project#56242.)
