tree.c (skip_simple_arithmetics_at, [...]): New functions.

        * tree.c (skip_simple_arithmetics_at, saved_expr_p): New functions.
        (save_expr): Replace loop by call to skip_simple_arithmetics_at.
        * tree.h: Add prototypes for the two new functions.
        * fold-const.c (fold_binary_op_with_conditional_arg): Replace test
        updates introduced in the previous revision by call to saved_expr_p.
        * stor-layout.c (put_pending_size): Use skip_simple_arithmetics_at.
