Simon Pilgrim 105e5c940c [ValueTracking] Add DemandedElts support to computeKnownBits/ComputeNumSignBits (PR36319) 
This patch adds initial support for a DemandedElts mask to the internal computeKnownBits/ComputeNumSignBits methods, matching the SelectionDAG and GlobalISel equivalents.

So far only a couple of instructions have been setup to handle the DemandedElts, the remainder still using the existing 'all elements' default. The plan is to extend support as we have test coverage.
