// FIXME: We can't re-use SelectionDAG patterns here because they match
// against a custom SDNode and we would need to create a generic machine
// instruction that is equivalent to the custom SDNode. This would also require
// us to custom legalize the intrinsic to the new generic machine instruction,
// but I can't get custom legalizing of intrinsic to work and I'm not sure if
// this is even supported yet.

// Since GlobalISel is more flexible then SelectionDAG, I think we can get
// away with adding patterns for integer types and not legalizing all
// loads and stores to vector types. This should help simplify the load/store
