  [Attributor] Prevent infinite loop in AAGlobalValueInfoFloating (#94941)

Global variables that reference themselves alongside a function that is
called indirectly can cause an infinite loop in
`AAGlobalValueInfoFloating`. The recursive reference is continually
pushed back into the workload, causing the attributor to hang
indefinitely.
