[LLVMdev] SplitVectorOp from CopyFromReg

I have a kernel that's swizzling a vector inside a loop. The vector was
created before the loop. The first node in the dag is an extract subvector
which calls into SplitVectorOp. The issue is that the node passed to it
comes from a CopyFromReg and SplitVectorOp doesn't know what to do. Is
there a reason why SplitVectorOp doesn't handle CopyFromReg nodes? If not,
can I submit a patch to add support?
