Support the comparison operators <, >, <=, and >= for values of enum types.

See http://tech.puredanger.com/java7#enum.

It is an oversight that you can't currently compare compatible enumeration values using the relational operators. When programmers want to compare enumeration values they either compare ordinals or use the compareTo method. This change would enable programmers to use the relational operators directly if the operands are of the same eumeration type.
