Gain ability know if a diff node has local changes
* include/abg-comparison.h (diff::has_local_changes): Add new pure
interface.
({decl_diff_base, type_diff_base, distinct_type_diff, var_diff,
pointer_diff, reference_diff, array_diff, qualified_type_diff,
enum_diff, class_diff, base_diff, scope_diff, function_decl_diff,
type_decl_diff, typedef_diff,
translation_unit_diff}::has_local_changes): Declare the
implementation of the pure interface above.
* src/abg-comparison.cc ({decl_diff_base, type_diff_base,
distinct_type_diff, var_diff, pointer_diff, reference_diff,
array_diff, qualified_type_diff, enum_diff, class_diff, base_diff,
scope_diff, function_decl_diff, type_decl_diff, typedef_diff,
translation_unit_diff}::has_local_changes): Define the
implementation of the pure interface above.
