// N.B.  This test verifies that two blocks which are otherwise
//       indistinguishable receive distinct manglings.
//       We had a bug where the first two blocks in the global block map could
//       get the same unqualified-block mangling because the logic to handle
//       block-ids believed it was handling Itanium-style discriminators.
