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.
PR target/82625
* 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.
