MI: Another -var-update bug?

[Nick Roberts <nickrob@snap.net.nz>]

Variable objects appear to test scope on a frame basis (in c_value_of root).
If we create a variable object for j in the inner block of the program below
then doing -var-update on line 10 doesn't report it as being out of scope.  But
struct varobj_root has a member struct block *valid_block.  Presumably the
addresses in this structure can be used to test if the variable is still in
scope or not
