829f2f24 - [VectorCombine] Mark function as changed if shuffle is created.

[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.
