Adapt to new CLAST structure within upstream CLooG version and retain compatibility to CLooG Legacy.

2010-07-27  Andreas Simbuerger  <simbuerg@fim.uni-passau.de>

	* graphite-clast-to-gimple.c (clast_name_to_gcc): Parameter
	type of NAME now depends on used CLooG version.
	(clast_to_gcc_expression): Replace expr_* with clast_expr_*.
	(gcc_type_for_clast_expr): Same.
	(print_clast_stmt): Replace pprint with clast_pprint.
	* graphite-cloog-compat.h: Provide compatibility macros for
	CLooG Legacy.
	(clast_name_p): New.
	(clast_expr_term): New.
	(clast_expr_red): New.
	(clast_expr_bin): New.
	(clast_pprint): New.
