Reduced memory usage of primitive fields smaller than 4-bytes
Reduced memory used by byte and boolean fields from 4 bytes down to a
single byte and shorts and chars down to two bytes. Fields are now
arranged as Reference followed by decreasing component sizes, with
fields shuffled forward as needed.
