org.renjin.compiler.ir.tac.expressions.Length
The length of an expression.
This is a bit annoying to add this to the set of expressions, but we need it to translate for expressions, because the length primitive is generic, but the for loop always uses the actual length of the vector. (is this another sign we need to push 'fors' down into the IR level?)

    IRLabel exitLabel = factory.newLabel();
       
    // initialize the counter
    factory.addStatement(new Assignment(counter, new Constant(0)));
    factory.addStatement(new Assignment(length, 
        new Length((Expression)vector)));


    // check the counter and potentially loop
    factory.addLabel(counterLabel);
    factory.addStatement(new IfStatement(new CmpGE(counter, length), exitLabel, bodyLabel));
