Andrea Di Biagio 4db1abea15 [DAG] Expose NoSignedWrap, NoUnsignedWrap and Exact flags to SelectionDAG. 
This patch modifies SelectionDAGBuilder to construct SDNodes with associated
NoSignedWrap, NoUnsignedWrap and Exact flags coming from IR BinaryOperator
instructions.

Added a new SDNode type called 'BinaryWithFlagsSDNode' to allow accessing
nsw/nuw/exact flags during codegen.

Patch by Marcello Maggioni.
