RFR: 8321823: Remove redundant PhaseGVN transform and transform_no_reclaim [v2]

[Joshua Cao]

> `PhaseGVN::transform` is just a one line wrapper around `PhaseGVN::transform_no_reclaim`. Looking at the history, they had different functionality in 2008, but since have become the same thing. We prefer to keep `PhaseGVN::transform` because it has hundreds of callsites, while the other only has a few callsites that are shown in the PR.
