RISC-V: Pattern name fix mul*3_highpart -> smul*3_highpart.

No known code changes, just fixes an inconsistency that was noticed.

	gcc/
	* config/riscv/riscv.md	(mulv<mode>4): Call gen_smul<mode>3_highpart.
	(<u>mulditi3): Call <su>muldi3_highpart.
	(<u>muldi3_highpart): Rename to <su>muldi3_highpart.
	(<u>mulsidi3): Call <su>mulsi3_highpart.
	(<u>mulsi3_highpart): Rename to <su>mulsi3_highpart.
