[Patch 1/2 AArch64/ARM] Give AArch64 ROR (Immediate) a new type attribute

gcc/

	* config/arm/types.md (type): Add rotate_imm.
	* config/aarch64/aarch64.md (*ror<mode>3_insn): Split out the
	ROR immediate case.
	(*rorsi3_insn_uxtw): Likewise.
	* config/aarch64/thunderx.md (thunderx_shift): Add rotate_imm.
	* config/arm/cortex-a53.md (cortex_a53_alu_shift): Add rotate_imm.
	* config/arm/cortex-a57.md (cortex_a53_alu): Add rotate_imm.
