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()

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
