Fangrui Song d69d981d77 [Tooling] -fsyntax-only adjuster: remove -c and -S ...

compile_commands.json entries often have -c. When adding -fsyntax-only,
we should remove -c to prevent the following warning:

```
% clang -c -fsyntax-only a.c
clang: warning: argument unused during compilation: '-c' [-Wunused-command-line-argument]
```

Previously, -c and -S were inappropriately claimed in
`addPGOAndCoverageFlags` (see the workaround added by commit
a07b135ce0). Now the workaround have been
removed (#98607). (clangDriver reports a -Wunused-command-line-argument
diagnostic for each unclaimed option.)

Fix #100909
