Allow lazy compilation (and thus optimisation) of functions inside eval.

Is there a particular reason we need two separate loops here?

Now using %OptimizeFunctionOnNextCall instead.

+for (var i = 0; i < 10000; ++i) foo();
 
-var a = [0, 1, 2, 3, 4, 5];
-assertTrue(%HasFastSmiElements(a));
-a.length = (1 << 30);
-assertFalse(%HasFastSmiElements(a));
-
+// Function should be optimized now.
+assertTrue(%GetOptimizationStatus(foo) != 2);
