  Log Message:
  -----------
  [mlir] add some FP classification ops and their lowering to libdevice (#127322)

Introduce a subset of floating point classification ops to the Math
dialect. These ops mirror functions provided by the C math library and,
similarly to the existing `math.copysign`, belong to the math dialect.
Add a lowering of those ops to Nvidia libdevice calls when possible as
the first mechanism to exercise them.
