This is based upon suggestions from David Bremner.

Committed to trunk.

gcc/

	* config/sparc/sparc.md (plusminus): New code iterator.
	(plusminus_insn): New code attr.
	(addv2si3, subv2si3, addv4hi3, subv4hi3, addv2hi3, subv2hi3): Merge
	using plusminus and plusminus_insn.
	(fpadd64_vis, fpsub64_vis): Likewise.
