6425 setup into 3 functions: init_float128_ibm, init_float128_ieee, and
6426 rs6000_init_libfuncs. If -mfloat128, add IFmode functions for all
6427 of the traditional names that TFmode uses for handling IEEE
6428 extended double. If -mfloat128, add KFmode functions for all of
6429 the emulation functions. If -mabi=ieeelongdouble and -mfloat128,
