c14fedd562 LibJS: Add bounds check to Array.prototype.{find,findIndex} 
The number of iterations is limited to the initial array size, but we
still need to check if the array did shrink since then before accessing
each element.

Fixes #1992.

80fecc615a LibJS: Add spreading in array literals 
Implement the syntax and behavor necessary to support array literals
such as [...[1, 2, 3]]. A type error is thrown if the target of the
spread operator does not evaluate to an array (though it should
eventually just check for an iterable).

Note that the spread token's name is TripleDot, since the '...' token is
used for two features: spread and rest. Calling it anything involving
'spread' or 'rest' would be a bit confusing.

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.
