[PATCH 2/6] rs6000: Use correct names for some trunc/extend libcalls

[Segher Boessenkool]

The libcalls for trunc and extend of a decimal float to a binary float,
and vice versa, do not have "2" in the name, although all other such
conversions do.


2018-07-16  Segher Boessenkool  <seg...@kernel.crashing.org>

        * config/rs6000/rs6000.c (init_float128_ibm): Use the correct names
        for conversions between IFmode and the decimal floating point modes.
        (init_float128_ieee): Use the correct names for conversions between
        KFmode and the decimal floating point modes.
