95abcc3722 LibJS: Implement correct object property ordering
This commit introduces a way to get an object's own properties in the
correct order. The "correct order" for JS object properties is first all
array-like index properties (numeric keys) sorted by insertion order,
followed by all string properties sorted by insertion order.

Objects also now print correctly in the repl! Before this commit:

courage ~/js-tests $ js
> ({ foo: 1, bar: 2, baz: 3 })
{ bar: 2, foo: 1, baz: 3 }

After:

courage ~/js-tests $ js
> ({ foo: 1, bar: 2, baz: 3 })
{ foo: 1, bar: 2, baz: 3 }

This simplifies the cell visiting functions by letting them not worry
about the pointers they pass to the visitor being null.

Also make the JS::Cell default constructor protected to provove a
compilation error if you tried to allocate a plain cell.
