Manually set dso_local when its valid to do so
This should have no real effect in most cases, as e.g. `hidden` visibility already implies `dso_local` (or at least LLVM IR does not preserve the `dso_local` setting if the item is already `hidden`), but it should fix `-Crelocation-model=static` and improve codegen in executables. Note that this PR does not exhaustively port the logic in [clang]. Only the obviously correct portion and what is necessary to fix a regression from LLVM 12 that relates to `-Crelocation_model=static`. Fixes #83335 [clang]: https://github.com/llvm/llvm-project/blob/3001d080c813da20b329303bf8f45451480e5905/clang/lib/CodeGen/CodeGenModule.cpp#L945-L1039
