    fix frange_nextafter odr violation
    
    C++ requires inline functions to be declared inline and defined in
    every translation unit that uses them.  frange_nextafter is used in
    gimple-range-op.cc but it's only defined as inline in
    range-op-float.cc.  Drop the extraneous inline specifier.
    
    Other non-static inline functions in range-op-float.cc are not
    referenced elsewhere, so I'm making them static.
    
    
    for  gcc/ChangeLog
    
            * range-op-float.cc (frange_nextafter): Drop inline.
            (frelop_early_resolve): Add static.
            (frange_float): Likewise.
