  Changed paths:
    A llvm/test/tools/llvm-reduce/remove-bbs-nocrash.ll
    M llvm/tools/llvm-reduce/deltas/ReduceBasicBlocks.cpp

  Log Message:
  -----------
  fix some bad logic that was removing all successor phi nodes, not just
out of chunk ones. the non-default second argument to
removePredecessor() is necessary to avoid creating invalid IR on
examples like the one in the provided test case
