[AArch64 array_mode 3/8] Stop using EImode in aarch64-simd.md and iterators.md

	* config/aarch64/aarch64-simd.md (aarch64_simd_ld3r<mode>):
	Change operand mode from <V_THREE_ELEM> to BLK.
	(aarch64_vec_load_lanesci_lane<mode>): Likewise.
	(aarch64_vec_store_lanesci_lane<mode>): Likewise.
	(aarch64_ld3r<mode>): Generate MEM rtx with BLKmode, call set_mem_size.
	(aarch64_ld3_lane<mode>): Likewise.
	(aarch64_st3_lane<mode>): Likewise.
	* config/aarch64/iterators.md (V_THREE_ELEM): Remove.
