Problem with use of TYPE_SIZE in tree optimizers

[Richard Kenner]

    A patch for this was already submitted but not approved/committed:
    <http://gcc.gnu.org/ml/gcc-patches/2004-10/msg01592.html>.
    And this is PR 18005.

That's what I'm re-running ACATS with.

But there's still the question of the similar reference in tree-mudflap.c.
