nir/opt_shrink_vectors: shrink some intrinsics from start
If the backend supports it, intrinsics with a component() are straightforward to
shrink from the start. Notably helps vectorized I/O.
v2: add an option for this and enable only on grown up backends, because some
backends ignore the component() parameter.
