  Changed paths:
    M clang/lib/Driver/ToolChains/Clang.cpp
    A clang/test/Driver/warn-fsyntax-only.c

  Log Message:
  -----------
  [Clang][Driver] Warn about `-c/-S` with `-fsyntax-only` (#98607)

Emit warning that `-S` and/or `-c` arguments are not used if
`-fsyntax-only` is also passed to clang
`addPGOAndCoverageFlags` is not the right place
to produce this warning
Now `-fsyntax-only -c/-S` combination handles like `-fsyntax-only -E` in
`BuildJobs()` driver function
