c5880356 - InstCombine: Reorder exp's known-nan source handling (#174417)

InstCombine: Reorder exp's known-nan source handling (#174417) In SimplifyDemandedFPClass, reorder the known-nan source handling above The known-zero-or-nan handling. The more specific cases need to be handled first. Avoids spurious diff in an upcoming patch for fadd support; this would introduce a simplifiable fadd when we can just go directly to the end result.
