    Original Commit Message:
    
        This switches the "code entry" field on JSFunction to no longer be an
        inner pointer into a Code object (i.e. to the start of the instruction
        stream), but a properly tagged pointer instead.
    
        Motivation behind this is the ability to treat this field regularly as
        part of escape analysis in the optimizing compiler. Also simplifies the
        object visitation for JSFunction objects.
