New Revision: 136757

URL: http://llvm.org/viewvc/llvm-project?rev=136757&view=rev
Log:
Small cleanups:
  - use SmallVectorImpl& for the function argument.
  - ignore the operands on the GEP, even if they aren't constant! Much as we
    pretend the malloc succeeds, we pretend that malloc + whatever-you-GEP'd-by
    is not null. It's magic!
