Log message:
	2004-04-23  Daniel Berlin  <dberlin@dberlin.org>
	
	* tree-loop-linear.c (linear_transform_loops): Add invariants array.
	* lambda-code.c (gcc_tree_to_linear_expression): Change arguments
	to include invariants array, and an int, instead of a bool.
	Handle invariants.
	(invariant_in_loop): New function.
	(gcc_loop_to_lambda_loop): Add support for invariants as bounds,
	and NE_EXPR tests.
	(gcc_loopnest_to_lambda_loopnest): Add invariants argument,
	init the invariants array, and pass it along to gcc_loop_to_lambda_loop.
	(lle_to_gcc_expression): Handle invariants and simple linear offsets.
	(lambda_loopnest_to_gcc_loopnest): Ditto.
	Also use the right test if the step is negative.
