Alexandros Lamprineas 5e1b99cf3b [SelectionDAG] swap select_cc operands to enable folding ...

The DAGCombiner tries to SimplifySelectCC as follows:

  select_cc(x, y, 16, 0, cc) -> shl(zext(set_cc(x, y, cc)), 4)

It can't cope with the situation of reordered operands:

  select_cc(x, y, 0, 16, cc)

In that case we just need to swap the operands and invert the Condition Code:

  select_cc(x, y, 16, 0, ~cc)
