[PATCH] D113214: [IR][ShuffleVector] Introduce `isReplicationMask()` matcher

[Jordan Rupprecht via Phabricator via llvm-commits]

Comment at: llvm/unittests/IR/InstructionsTest.cpp:1133
+
+TEST(InstructionsTest, ShuffleMaskIsReplicationMask_undef) {
+  for (int ReplicationFactor : seq_inclusive(1, 6)) {
