ycm_extra_conf.py files used to import clang_helpers and then use the PrepareClangFlags function; this is now unnecessary since the logic from that function has been moved to flags.py. The old PrepareClangFlags function is still there (it just returns the flags it gets) for the sake of backwards compatibility with old ycm_extra_conf.py files.
