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

[Segher Boessenkool <segher at kernel dot crashing dot org>]

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  <segher@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.
