	PR tree-optimization/37375
	* tree-scalar-evolution.c (scev_info_str): Add field instantiated_below.
	(new_scev_info_str, eq_scev_info, find_var_scev_info,
	set_scalar_evolution, get_scalar_evolution, get_instantiated_value,
	set_instantiated_value): Pass instantiated_below.
	(analyze_scalar_evolution_1, analyze_scalar_evolution): Update calls to
	above functions.
	(instantiate_scev_1, instantiate_scev): Pass a basic block above which the
	definitions are not instantiated.

	* tree-scalar-evolution.h (instantiate_scev): Update declaration.
	(block_before_loop): New.
	* tree-data-ref.c (dr_analyze_indices): Update uses of instantiate_scev.
	* graphite.c (block_before_scop): New.
	(loop_affine_expr, stmt_simple_for_scop_p, harmful_stmt_in_bb): Pass a 
	basic block, not a loop for determining the parameters.
	(scopdet_edge_info, build_scops_1): Do not pass outermost loop in the
	scop.
	(idx_record_params, find_params_in_bb, find_scop_parameters,
	build_loop_iteration_domains, add_conditions_to_domain): Update calls 
	to instantiate_scev.
	
	* Makefile.in (cfgloopmanip.o): Add missing dependency on TREE_FLOW_H.
