Array.reserve

Reserve enough memory from the allocator to store n elements. If the current capacity exceeds n nothing will happen. If n exceeds the current capacity, an attempt to expand the current array is made. If expand is successful, all the expanded elements are default initialized to T.init. If the expand fails a new buffer will be allocated, the old elements of the array will be copied and the new elements will be default initialized to T.init.
