lambda_loopnest_transform, lambda_loopnest_to_gcc_loopnest calls
and free afterwards.
* lambda.h (struct obstack): New forward declaration.

allocation of ret.
(lambda_body_vector_new): Likewise.
(lambda_linear_expression_new): Likewise.

Pass it to gcc_loop_to_lambda_loop and lambda_loopnest_new.
(lambda_loopnest_to_gcc_loopnest): New parameter lambda_obstack.
Pass it to lambda_body_vector_new and
lambda_body_vector_compute_new.
* Makefile.in (tree-loop-linear.o): Add $(OBSTACK_H) dependency.
(lambda-code.o): Likewise.
