patch (670ebafda11a)

After bug 750834 scripts can now have up to four JITScripts simultaneously (normal/ctor versions with or without barriers), bloating the number of handles stored in the JSScript itself.  Usually, all these fields are NULL, so it would be better if the handles were stored in a separate structure which is non-NULL if the script has had any JIT activity (purging the structure whenever all JIT code for the script is released).
