computeKnownFPClass already accepts a `const APInt &DemandedElts` argument to allow us to specify demanded vector elements (or `APInt(1,1)` for scalar/scalable types) - and has a simple computeKnownFPClass wrapper for when the DemandedElts arg wasn't necessary/available.
We need to add similar handling and wrappers to SimplifyDemandedFPClass to allow us to improve vector analysis and optimisation (shufflevector, insertelement, extractelement etc.).
