arm: [MVE intrinsics] factorize several binary _m_n operations

Factorize vhaddq_m_n, vhsubq_m_n, vmlaq_m_n, vmlasq_m_n, vqaddq_m_n,
vqdmlahq_m_n, vqdmlashq_m_n, vqdmulhq_m_n, vqrdmlahq_m_n,
vqrdmlashq_m_n, vqrdmulhq_m_n, vqsubq_m_n
so that they use the same pattern.

	gcc/
	* config/arm/iterators.md (MVE_INT_SU_M_N_BINARY): New.
	(mve_insn): Add vhaddq, vhsubq, vmlaq, vmlasq, vqaddq, vqdmlahq,
	vqdmlashq, vqdmulhq, vqrdmlahq, vqrdmlashq, vqrdmulhq, vqsubq.
	(supf): Add VQDMLAHQ_M_N_S, VQDMLASHQ_M_N_S, VQRDMLAHQ_M_N_S,
	VQRDMLASHQ_M_N_S, VQDMULHQ_M_N_S, VQRDMULHQ_M_N_S.
	* config/arm/mve.md (mve_vhaddq_m_n_<supf><mode>)
	(mve_vhsubq_m_n_<supf><mode>, mve_vmlaq_m_n_<supf><mode>)
