	* lambda.h (lambda_matrix_new, lambda_matrix_inverse): New
	argument lambda_obstack.
	* lambda-code.c (lambda_lattice_new): Pass lambda_obstack to
	lambda_matrix_new.
	(compute_nest_using_fourier_motzkin): Likewise.
	(lambda_compute_auxillary_space): Likewise.
	(lambda_compute_step_signs): Likewise.
	(lambda_compute_target_space): Pass lambda_obstack to
	lambda_matrix_new and lambda_matrix_inverse.
	(lambda_loopnest_transform): Pass lambda_obstack to
	lambda_compute_step_signs and lambda_matrix_new.
	(lambda_matrix_project_to_null): Remove.
	* tree-data-ref.c (analyze_subscript_affine_affine): New variable
	scratch_obstack.  Initialize obstack, pass it to
	lambda_matrix_new, destroy obstack.
	* lambda-trans.c (lambda_trans_matrix_new): Pass lambda_obstack to
	lambda_matrix_new.
	(lambda_trans_matrix_inverse): Pass lambda_obstack to
	lambda_matrix_inverse.
	* lambda-mat.c (lambda_matrix_get_column): Remove.
	(lambda_matrix_new): New argument lambda_obstack.  Use obstack
	allocation instead of GGC_NEWVEC.
	(lambda_matrix_inverse_hard, lambda_matrix_inverse): New argument
	lambda_obstack.
	(lambda_matrix_project_to_null): Remove.
