Patch to allow Ada to work with tree-ssa

[Richard Kenner]

    I'll provide a more detailed diagnosis tomorrow.  It's quite possible,
    of course, that you've revealed a bug in the Java gimplification code.

No, I think it's the case I mentioned in my last message.  If so, not too
bad to fix.

I don't know how to run Java code, though.  Can you tell me the command-line
options I need with the file you provided to see the problem?
