Current InterpreterCodelet lays the field in inefficient order:
sizeof: 24
_size: @0
_description: @8
_bytecode: @16
Stub generation aligns codelets and their related code at CodeEntryAlignment, which means with CEA=16 we are taking two CEA units for InterpreterCodelet data. Rearranging the fields a bit improves the interpreter code density a bit, dropping its sizeof to 16 and thus taking one CEA unit.
