[9] RFR(S): JDK-8039498: Add iterators to GrowableArray

[Vitaly Davidovich]

I would add a few asserts:

1) verify that position provided to iterator is within valid range
2) equality operators should verify that both iterators point to same GA
instances

These are pedantic given how these iterators will be used, but wouldn't
hurt, IMHO.
