説明
This will need to be based off the implementation in computeKnownFPClass in ValueTracking.cpp.
Hopefully once https://github.com/llvm/llvm-project/pull/189476 lands the ISD::SINT_TO_FP/UINT_TO_FP handling can be removed from DAG.isKnownNeverNaN and the generic fallback to computeKnownFPClass can be used instead.
Must include DemandedElts handling and IR test coverage.
