Do not allocate stmt_vec_info for labels

The following avoids allocating stmt_vec_info for labels.

	* tree-vect-loop.cc (_loop_vec_info::_loop_vec_info): Also
	skip labels.
	* tree-vect-slp.cc (_bb_vec_info::_bb_vec_info): Likewise.
	* tree-vect-data-refs.cc (vect_analyze_early_break_dependences):
	Skip labels.
