rs6000: Set up ieee128_float_type_node correctly (PR82625)

We shouldn't init __ieee128 to be the same as long double if the
latter is not even a 128-bit type.

This also reorders the nearby __ibm128 code so both types use similar
logic.

        * config/rs6000/rs6000.c (rs6000_init_builtins): Do not set
        ieee128_float_type_node to long_double_type_node unless
        TARGET_LONG_DOUBLE_128 is set.
