Sanjay Patel a06d989552 [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.
