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 a07b135ce0c0111bd83450b5dc29ef0381cdbc39). Now the workaround have been removed (#98607). (clangDriver reports a -Wunused-command-line-argument diagnostic for each unclaimed option.)
