Sanjay Patel 4cc3c35fb0 [ValueTracking] improve ComputeNumSignBits for vector constants ... This is similar to the computeKnownBits improvement in rL268479. There's probably more we can do for vector logic instructions, but this should let us see non-splat constant masking ops that can become vector selects instead of and/andn/or sequences.
