The implementation in this PR, the driver accepts `-fno-profile-generate` option but does not forward it to -fc1. However, I still handled the option in `CompilerInvocation.cpp` so that a direct `-fc1 -fno-profile-generate` invocation does not result in an "unknown argument" error.

Before proceeding further, I would like to understand the intended design for such options. Once we align on the expected behavior, I will  update the implementation accordingly.
