        Fix 64-bit varargs for Darwin (Radar 4028089).
        * config/rs6000/rs6000.h (rs6000_args): New field floats_in_gpr.
        * config/rs6000/rs6000.c (rs6000_darwin64_record_arg_advance_flush):
        Add argument, add case for 8-byte register half-filled with a float.
        (rs6000_darwin64_record_arg_advance_recurse): Detect and handle
        single-precision floats specially.
