AOT generator misses assignments in object initializer expressions

[Sergio0694]

Description

It seems object initializer expressions throw off the generator, which misses types being assigned to properties.

Steps To Reproduce

Something like this:

class A
{
    public IEnumerable<string> Items { get; set; }
}

class B<T> : List<T>;

var obj = new A()
{
    Items = new B<string>(); // Generator misses this
};

Expected Behavior

B<string> should show up in the global CCW vtable.
