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.
