[DAG] Improve FMINNUM/FMAXNUM/FMINIMUM/FMAXIMUM constant folding
Merge the node combines into a common DAGCombiner::visitFMinMax (like we do for IMINMAX).
Move the constant folding into SelectionDAG::foldConstantFPMath.
This allows us to fold the vecreduce-propagate-sd-flags.ll test as it reduces constants - so I've refactored it to take variables instead.
