2778d077e5 LibJS: Grow storage when adding a property to uniquely-shaped Object 
Normally the storage would be expanded by set_shape() upon transition
to a new shape, but if the shape is already unique, there is no new
transition so we have to expand the storage manually.

f897c41092 LibJS: Implement basic support for the "delete" operator 
It turns out "delete" is actually a unary op :)
This patch implements deletion of object properties, it doesn't yet
work for casually deleting properties from the global object.

When deleting a property from an object, we switch that object to
having a unique shape, no longer sharing shapes with others.
Once an object has a unique shape, it no longer needs to care about
shape transitions.

38ba13e912 LibJS: Implement Object.is() 
Basically === with two particularities: comparing NaN to itself is
considered equal and comparing +0 and -0 is not.

This allows us to run "run-tests -g" for testing with GC after every
heap allocation. This may flush out bugs that would otherwise not
occur if GC'ing only occasionally.
