  [X86] collectConcatOps - add ability to recurse through insert_subvector chains

Allows us to match insert_subvector(insert_subvector(undef, insert_subvector(insert_subvector(undef, x, 0), y, 1), 0), 0),
                                    insert_subvector(insert_subvector(undef, z, 0), w, 1), 2)
