Replace EEOP_DONE with special steps for return/no return Knowing when the side-effects of an expression is the intended result of the execution, rather than the returnvalue, is important for being able generate more efficient JITed code. This replaces EEOP_DONE with two new steps: EEOP_DONE_RETURN and EEOP_DONE_NO_RETURN. Expressions which return a value should use the former step; expressions used for their side-effects which don't return value should use the latter.
