  [SelectionDAG] Fix lowering of IEEE 754 2019 minimum/maximum

We used integer comparisons instead of floating point comparisons
resulting in very odd behavior.

    M llvm/test/CodeGen/NVPTX/bf16-instructions.ll

  Log Message:
  -----------
  [NVPTX] Fix bugs involving maximum/minimum and bf16

We would crash on sufficiently old NV hardware (Volta or so) due to
incorrectly marking certain operations legal.
