variable.c: avoid compatibility table with generic ivars This recovers and improves performance of Marshal.dump/load on Time objects compared to when we implemented generic ivars entirely using st_table. This also recovers some performance on other generic ivar objects, but does not bring bring Marshal.dump/load performance up to previous speeds. benchmark results: minimum results in each 10 measurements.
