   2 # - Relocation against base of .xdata record, immediate offset in .pdata
   3 #   (what LLVM produces)
   4 # - Relocation against symbol in .xdata, no immediate offset in .pdata
   5 #   (what MSVC produces)
   6 # - Combination of the two above (unlikely to occur in the wild, but for
   7 #   testing the consistency of the code)
