Revert "Avoid maxnum(sNaN, x) optimizations / folds (#170181)" (#184125) ...

This reverts commit ea3fdc5972db7f2d459e543307af05c357f2be26.

Re-enable const-folding for maxnum/minnum in the middle-end, GlobalISel,
and SelectionDAG.

Re-enable optimizations that depend on maxnum/minnum sNaN semantics in
InstCombine and DAGCombiner.

Now that maxnum(x, sNaN) is specified to non-deterministically produce
either NaN or x, these constant-foldings and optimizations are now valid
again according to the newly clarified semantics in #172012 .
