	assign_copy_secondary, assign_secondary, unassign_copy_secondary,
	unassign_secondary, free_secondary_copy_changes,
	secondary_copy_change_varray): Rename to correspondingly
	initiate_copy_changes, free_copy_change, get_free_copy_change,
	finish_copy_changes, assign_copy, assign_allocno_copies,
	unassign_copy, unassign_allocno_copies, free_copy_changes,
	copy_change_varray.
	(get_free_copy_change): Initialize interm_equiv_const_regno and
	interm_equiv_const_mode.
	(assign_copy_interm_equiv_const_hard_reg,
	unassign_copy_interm_equiv_const_hard_reg): New functions.
	(assign_copy, unassign_copy): Take equivalent constant into
	account.
	(unassign_one_allocno): Call unassign_allocno_copies when the
	equivalent constant is used.
	(check_elimination_in_addr): New parameters.
	(get_equiv_const_addr_info, get_equiv_const_elimination_info): New
	functions.
	(undo_copy_change): Process interm_equiv_const_regno.

	into account.

	* yara-ir.c: Rename COPY_SECONDARY_CHANGE_ADDR to
	COPY_CHANGE_ADDR.  Remove HAVE_ANY_SECONDARY_MOVES.
	(print_copy): Print new fields interm_equiv_const_regno and
	interm_equiv_const_mode.
	(make_aggressive_coalescing): Prevent coalescing cans with
	equivalent constants.
