  Changed paths:
    M llvm/lib/Transforms/IPO/GlobalOpt.cpp
    A llvm/test/Transforms/GlobalOpt/malloc-promote-6.ll

  Log Message:
  [GlobalOpt] Iterate over replaced values deterministically to constprop

If there are pre-existing dead instructions, the order we visit replaced
values can cause us sometimes to not delete dead instructions.

The added test non-deterministically failed without the change.
