Fix PR47127: call cloog_state_malloc and cloog_state_free only once.

2011-03-12  Sebastian Pop  <sebastian.pop@amd.com>

	PR tree-optimization/47127
	* graphite-clast-to-gimple.c (build_cloog_prog): Removed state
	parameter.
	(set_cloog_options): Same.
	(scop_to_clast): Same.
	(print_clast_stmt): Do not call cloog_state_malloc and
	cloog_state_free.
	(print_generated_program): Same.
	(gloog): Same.
	* graphite-clast-to-gimple.h (cloog_state): Declared.
	(scop_to_clast): Adjust declaration.
	* graphite.c (cloog_state): Defined here.
	(graphite_initialize): Call cloog_state_malloc.
	(graphite_finalize): Call cloog_state_free.
