This fix checks the original LLVM IR node to identify opaque constants by looking for the bitcast-constant pattern. Originally we looked at the generated SDNode, but this might lead to incorrect results. The SDNode could have been generated by an constant expression that was folded to a constant. This fixes <rdar://problem/16050719> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201291 91177308-0d34-0410-b5e6-96231b3b80d8
