Jin-Gu Kang 0bf8241d4b Added checking code whehter target supports specific dag combining about rotate 
or not. The corresponding dag patterns are as following:

"DAGCombier::MatchRotate" function in DAGCombiner.cpp
Pattern1
// fold (or (shl (*ext x), (*ext y)),
//          (srl (*ext x), (*ext (sub 32, y)))) ->
//   (*ext (rotl x, y))
// fold (or (shl (*ext x), (*ext y)),
//          (srl (*ext x), (*ext (sub 32, y)))) ->
//   (*ext (rotr x, (sub 32, y)))

pattern2
// fold (or (shl (*ext x), (*ext (sub 32, y))),
//          (srl (*ext x), (*ext y))) ->
//   (*ext (rotl x, y))
// fold (or (shl (*ext x), (*ext (sub 32, y))),
//          (srl (*ext x), (*ext y))) ->
//   (*ext (rotr x, (sub 32, y)))
