[PATCH] D28351: AMDGPU: Remove spurious out branches after a kill

[Samuel Pitoiset via Phabricator via llvm-commits]

No. Currently the code will become:

  V_CMPX
  S_BRANCH BB#other
  S_CBRANCH_EXECNZ BB#next

Because S_CBRANCH_EXECNZ is added as terminator.

That's why my first was idea was to remove the unconditional branch *after* the kill.

I wrote a MIR test. I should probably send a new revision with the test.
