Bogous trees in ivopts again!

[Richard Guenther]

The problem is (?) that get_base_address for

 state_inD.6032_16->savedD.6026[regD.6037_3]

(which is of type <integer_type 0x4014a3cc char>)
returns

 *state_inD.6032_16

(which is of type <record_type 0x4040621c>).

The documentation of get_base_address does not talk about any
type guarantees - but I guess IVOPTs rather wanted to have

 state_inD.6032_16->savedD.6026[0]

?

I don't understand the global picture here - i.e. what rewrite_address_base
is actually trying to do here.
