[llvm-commits] [PATCH] Add a new visitor for walking the uses of a pointer value.

[Chandler Carruth]

  Simplify the interface for enqueuing users to more accurately reflect the
  common use case. Just mutate the offset of during the visit when walking a GEP.
  This fixes several miscompiles where we would lose the fact that the offset was
  unknown when round-tripping through a bitcast or a GEP.
