Subject: function.h (struct sequence_stack): Remove rtl_expr.

	* function.h (struct sequence_stack): Remove rtl_expr.
	(struct emit_staus): Likewise.
	(seq_rtl_expr): Remove.
	* tree.h (free_temps_for_rtl_expr): Don't declare.
	(start_sequence_for_rtl_expr): Likewise.
	* rtl.h (preserve_rtl_expr_result): Likewise.
	* emit-rtl.c (start_sequence): Don't set sequence_rtl_expr.
	(start_sequence_for_rtl_expr): Remove.
	(push_topmost_sequence): Don't save sequence_rtl_expr.
	(pop_topmost_sequence): Remove comment about not restoring it.
	(end_sequence): Don't set seq_rtl_expr.
	(init_emit): Don't initialize it.
	(mark_sequence_stack): Don't mark it.
	(mark_emit_status): Likewise.
	* except.c (protect_with_terminate): Use
	start_sequence_for_rtl_expr, not start_sequence.
	* expr.c (expand_expr, case RTL_EXPR): Don't call
	preserve_rtl_expr_result or free_temps_for_rtl_expr.
	(assign_stack_temp_for_type): Don't set rtl_expr.
	(preserve_rtl_expr_result): Remove.
	(free_temps_for_rtl_expr): Likewise.
	(pop_temp_slots): Likewise.
	(mark_temp_slot): Don't mark the rtl_expr.
	* stmt.c (expand_start_stmt_expr): Use start_sequence, not
	start_sequence_for_rtl_expr.
