(enum ia64_script_insn_opcode): Moved to here from script.h. 	Added operations IA64_INSN_ADD_PSP_NAT, IA64_INSN_ADD_SP_NAT, 	IA64_INSN_MOVE_NAT, IA64_INSN_MOVE_NO_NAT, 	IA64_INSN_MOVE_STACKED_NAT, IA64_INSN_MOVE_STACKED_NAT, 	IA64_INSN_MOVE_SCRATCH_NAT, and IA64_INSN_MOVE_SCRATCH_NO_NAT. (emit_nat_info): Remove---it's no longer needed. (compile_reg): Emit special op-codes when compiling a preserved 	static register, such that it's NaT-info can be updated. (set_nat_info): New function. (run_script): Implement new script instructions.
