説明

ISD::FMAXIMUM/ISD::FMINIMUM + ISD::FMAXIMUMNUM/ISD::FMINIMUMNUM handling can be added as well

This will need to be based off the implementation in computeKnownFPClass in ValueTracking.cpp - DenormalMode access might take some additional patches / test coverage

This should be tested with IR tests and not unit tests
