[NVPTX] Make sure we do not generate MULWIDE ISD nodes when optimizations are disabled 

With optimizations disabled, we disable the isel patterns for mul.wide; but we
were still generating MULWIDE ISD nodes.  Now, we only try to generate MULWIDE
ISD nodes in DAGCombine if the optimization level is not zero.
