    scanner: Add _Float128
    
    The ISO/IEC TS 18661-3:2015 standard added new floating point types to
    the C standard.
    
    Newer versions of the GNU C library started exposing `_Float128` in the
    headers, which means we need to add this type to the known tokens, to
    avoid warnings.
