	* gcc-interface/gigi.h (create_index_type): Adjust head comment.
	* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Signed_Integer_Subtype>:
	Use front-end predicates to compute signedness and precision.
	<E_String_Literal_Subtype>: Fold range type.
	Make sure to set longest_float_type_node to a scalar type.
	(elaborate_entity): Use consistent Constraint_Error spelling.
	(substitute_in_type) <INTEGER_TYPE>: Always copy the type.
	* gcc-interface/misc.c (gnat_print_type) <INTEGER_TYPE>: Use brief
	output for the modulus, if any.
	<ENUMERAL_TYPE>: Likewise for the RM size.
	* gcc-interface/trans.c (gnat_to_gnu): Use consistent Constraint_Error
	spelling.
	* gcc-interface/utils.c (finish_record_type): Really test the alignment
	of BLKmode bit-fields to compute their addressability.
	(create_index_type): Adjust comments.
	(create_param_decl): Create the biased subtype manually.
	* gcc-interface/utils2.c (build_component_ref): Use consistent
	Constraint_Error spelling.
