------- Additional Comments from Zoltan Herczeg <zherczeg at inf.u-szeged.hu>
I split the patch into two parts for easier review.

Since my mthod detects Math.floor(a/b) expressions in AST level, I need some
kind of node type. I decided to use virtual methods for this task, because
emitByteCode has already virtual, so virtual method table has already generated
for all nodes.

Perhaps some virtual functions can be eliminated in ExpressionNode using these
types.
