    rs6000: Clean up TF and TD check with FLOAT128_2REG_P
    
    Commit r6-2116-g2c83faf86827bf did some clean up on TFmode
    and TFmode check with FLOAT128_2REG_P, but it missed to
    update an assertion, this patch is to make it align.
    
    btw, it's noticed when I'm making a patch to get rid of
    TFmode.
    
    gcc/ChangeLog:
    
            * config/rs6000/rs6000-call.cc (rs6000_darwin64_record_arg_recurse):
            Clean up TFmode and TDmode check with FLOAT128_2REG_P.
