I would like to have this but it's not as easy to do as verify_oop().  
The Metaspace::contains() function does range checks for all the virtual 
spaces that have been mmap'ed but this is not just one range like the oops.

Maybe we should have verify_method() do something like verify *ptr == 
the vtable for Method, similarly for Klass.   I will file an RFE for this.
