Problem with operand handling

[Richard Kenner]

    The only time &var is used as a pointer is if the variable passes the
    test 'is_gimple_reg()'.  Only real operands store this pointer value. 
    If var is a virtual SSA_NAME operand, then we store *var into a tree and
    keep that value around.

I think this is pre-ssa-conversion, so it's still a VAR_DECL.  I didn't
see any code to do that copying.

    So this should only be causing you a problem if you have an
    is_gimple_reg() which is being passed to add_stmt_operand in this
    manner. The thats a bug.

It was happening via a TMT "variable".
