(const_str_type_node): New #define.
* config/rs6000/rs6000.md (copysign<mode>3 for IEEE128): Convert
to a define_expand that dispatches to either copysign<mode>3_soft
or copysign<mode>3_hard.
(copysign<mode>3_hard): Rename from copysign<mode>3.
(copysign<mode>3_soft): New define_insn.
* doc/extend.texi: Document new builtins.
