Instead of just using regular struct lowering for these types, which results in an incorrect ABI (e.g. returning indirectly), use `BackendRepr::ScalableVector` which will lower to the correct type and be passed in registers. This also enables some simplifications for generating alloca of scalable vectors and greater re-use of `scalable_vector_parts`. A LLVM codegen test demonstrating the changed IR this generates is included in the next commit alongside some intrinsics that make these tuples usable.
