iteratee added a comment.

The following 4 tests don't have an obvious fix with this test. I was hoping to get some help by the test authors.

  LLVM :: CodeGen/Thumb2/v8_IT_5.ll
  LLVM :: CodeGen/WebAssembly/cfg-stackify.ll
  LLVM :: CodeGen/X86/licm-dominance.ll
  LLVM :: CodeGen/X86/wineh-coreclr.ll

licm-dominance is a real pain because the undefineds get loop-optimized away and invalidate the test assumptions. It looks like it was never correct.
