    gcn: Update --with-arch= for newer archs
    
    Replace hard-coded list of supported devices by directly checking
    config/gcn/gcn-devices.def.
    
    gcc/ChangeLog:
    
            * config.gcc (--with-{arch,tune}): Use .def file to validate gcn
            processor names.
            * doc/install.texi (amdgcn*-*-*): Update list of devices supported
            by --with-arch/--with-tune.
