Mehdi Amini 5059813c2d DAGCombine: always constant fold FMA when target disable FP exceptions 
Summary: When trying to constant fold an FMA in the DAG, getNode()
fails to fold the FMA if an operand is not finite. In this case this
patch allows the constant folding if !TLI->hasFloatingPointExceptions()
