Think the last two should simplify to op0 and op3, which I guess
means recursing on the "return XEXP (x, op);"
I thought about doing that, but I noticed that, for example,
simplify_gen_unary does not recurse into its operand. Is that an
omission, or is it expected that those operands will already have been
simplified?
