emit-rtl.c (init_emit): Use ggc_alloc for regno_reg_rtx.

	* emit-rtl.c (init_emit): Use ggc_alloc for regno_reg_rtx.
	* function.h (struct emit_status): Length of regno_pointer_align
	and x_regno_reg_rtx as seen by gengtype is only x_reg_rtx_no,
	not regno_pointer_align_length (i.e. length actually used, not
	length as allocated)

	* config/i386/i386.c (struct stack_local_entry): New.
	(struct machine_function): Replace huge array with alist.
	(assign_386_stack_local): Change to match.
