	* testsuite/gcc.dg/graphite/scop-16.c: Test only scop specific info.
	* testsuite/gcc.dg/graphite/scop-17.c: Same.
	* testsuite/gcc.dg/graphite/block-5.c: New.
	* testsuite/gcc.dg/graphite/block-6.c: New.
	* testsuite/gcc.dg/graphite/pr37485.c: Clean dump file after.
	* testsuite/gcc.dg/graphite/pr37684.c: Same.
	* testsuite/gcc.dg/graphite/block-2.c: Same.

	* graphite.c (struct ivtype_map_elt): New.
	(debug_ivtype_elt, debug_ivtype_map_1, debug_ivtype_map,
	new_ivtype_map_elt, ivtype_map_elt_info, eq_ivtype_map_elts,
	gcc_type_for_cloog_iv): New.
	(loop_iv_stack_patch_for_consts): Use the type of the induction
	variable from the original loop, except for the automatically
	generated loops, i.e., in the case of a strip-mined loop, in
	which case there is no original loop: in that case just use
	integer_type_node.
	(new_graphite_bb): Initialize GBB_CLOOG_IV_TYPES.
	(free_graphite_bb): Free GBB_CLOOG_IV_TYPES.
	(clast_name_to_gcc): Accept params to be NULL.
	(clast_to_gcc_expression): Take an extra parameter for the type.
	Convert to that type all the expressions built by this function.
	(gcc_type_for_clast_expr, gcc_type_for_clast_eq): New.
	(graphite_translate_clast_equation): Compute the type of the
	clast_equation before translating its LHS and RHS.
	(clast_get_body_of_loop, gcc_type_for_iv_of_clast_loop): New.
	(graphite_create_new_loop): Compute the type of the induction
	variable before translating the lower and upper bounds and before
	creating the induction variable.
	(rename_variables_from_edge, rename_phis_end_scop): New.
	(copy_bb_and_scalar_dependences): Call rename_phis_end_scop.
	(sese_add_exit_phis_edge): Do not use integer_zero_node.
	(find_cloog_iv_in_expr, compute_cloog_iv_types_1,
	compute_cloog_iv_types): New.
	(gloog): Call compute_cloog_iv_types before starting the
	translation of the clast.

	* graphite.h (struct graphite_bb): New field cloog_iv_types.
	(GBB_CLOOG_IV_TYPES): New.
	(debug_ivtype_map): Declared.
	(oldiv_for_loop): New.
