	* tree-vect-data-refs.c (vect_analyze_data_refs): For clobbers, call
	free_data_ref on the dr first, and before goto again also set dr
	to the next dr.  For simd_lane_access, free old datarefs[i] before
	overwriting it.  For get_vectype_for_scalar_type failure, don't
	free_data_ref if simd_lane_access.
