Add a per-runtime loop attribute table that associates a jsval attribute with every loop in the code. The jsval is used initially as a counter until a certain threshold is reached, at which point the loop is traced and compiled and the resulting native code object is stored in the jsval to be executed for future encounters of the loop.
