Summary: Add support for TupleGetOp folding through InsertSlicesOp and ExtractSlicesOp. Vector-to-vector transformations for unrolling and lowering to hardware vectors can generate chains of structured vector operations (InsertSlicesOp, ExtractSlicesOp and ShapeCastOp) between the producer of a hardware vector value and its consumer. Because InsertSlicesOp, ExtractSlicesOp and ShapeCastOp are structured, we can track the location (tuple index and vector offsets) of the consumer vector value through the chain of structured operations to the producer, enabling a much more powerful producer-consumer fowarding of values through structured ops and tuple, which in turn enables a more powerful TupleGetOp folding transformation.
