  -----------
  [GlobalDCE] [VFE] Add a test for incorrect VFE behavior in presence of null/invalid vtable entries

Add a test for VFE where there's several vtables, and one of them contains an
invalid entry (from VFE's perspective), and which causes VFE to incorrectly skip
scanning subsequent vtables and drop their dependencies.
