  [flang][debug] Improve check for global variable detection. (#118326)

When a global variable is used in the OpenMP target region, it is passed
as an argument to the function that implements target region. But the
`DeclareOp` for this incarnation still have the original name of the
variable. As some of our checks to decide if a variable is global or nor
are based on the name, this can result in a local variable being treated
as global. This PR hardens the check a bit. We now also check that
memory ref is actually an `AddrOfOp` before looking at the name.
