After https://github.com/llvm/llvm-project/pull/101103, `-S` and `-c` options seem to be incompatible when using -Werror. This doesn't seem to be intentional, from what I can tell.
The following program results in `clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]`
```
touch foo.c
~/llvm-project/build/bin/clang -S -O0 -Werror -c .foo.c -o foo.c.o
```
