Your patch causes regression in the Fortran frontend

[Richard Kenner]

    Could this be related to the problem Kenner found yesterday with
    inlining and shared INTEGER_CST nodes being incorrectly modified
    during inlining?

Seems very highly unlikely to me since the problem I ran into should
only affect types that have variable bounds and I don't think Fortran
does that.  Also, that ICE is very specific.

In any event, I'm about to check in the fix for the problem I found,
so you'll know for sure then.
