* m68hc11_sim.c (cpu_special): Handle call and rtc instructions.

	* sim-main.h (M6812_CALL_INDIRECT): Add to enum.
	(m6811_regs): Add page register.
	(cpu_set_page, cpu_get_page): New macros.
	(phys_to_virt): New function.
	(cpu_get_indexed_operand_addr, cpu_return): Declare.
	* gencode.c: Identify indirect addressing mode for call and fix daa.
	(gen_function_entry): New param to tell if src8/dst8 locals are
	necessary.
	(gen_interpreter): Use it to avoid generation of unused variables.
	* interp.c (sim_fetch_register): Allow to read page register; page
	register, A, B and CCR are only 1 byte wide.
	(sim_store_register): Likewise for writing.
