thopre added a comment.

LGTM (besides comment fix) but I'm not too familiar with the vector side of

================
Comment at: llvm/lib/CodeGen/SelectionDAG/TargetLowering.cpp:6967
+  // NaN has all exp bits set and a non zero significand. Therefore:
+  // isnan(V) == ((exp mask - (abs(V) & exp mask)) < 0)
+  unsigned BitSize = OperandVT.getScalarSizeInBits();
