Implement Enumerator objects on VWA
This commit implements Enumerator objects on VWA. This speeds allocations and decreases memory usage. ``` require "benchmark" ary = [] puts(Benchmark.measure do 10_000_000.times do u = ary.to_enum end end) puts `ps -o rss= -p #{$$}` ``` Before: ``` 1.500774 0.002717 1.503491 ( 1.506791) 18512 ``` After: ``` 0.892580 0.002539 0.895119 ( 0.897642) 16480 ```
