Original Commit Message:

    The "Address" type is V8's general-purpose type for manipulating memory
    addresses. Per the C++ spec, pointer arithmetic and pointer comparisons
    are undefined behavior except within the same array; since we generally
    don't operate within a C++ array, our general-purpose type shouldn't be
    a pointer type.
