[RFA/MI testsuite] test varobj type changing

[Keith Seitz <keiths@redhat.com>]

Hi,

Varobj can track the name of a variable through different frames. With MI 
this is specified by giving -var-create the special frame flag "@". 
Whenever the type of the variable changes, then, MI informs the user that 
this has happened.

I've added a brief test to make sure that this is working properly.
