  Log Message:
  -----------
  [VectorCombine] Mark function as changed if shuffle is created.

777d6b5de90b7e0 exposed a code path where a function is modified but not
marked accordingly. Make sure we return true from foldShuffleFromReductions
if only a shuffle has been inserted/replaced.

Should fix    https://lab.llvm.org/buildbot/#/builders/187/builds/7578.
