Summary: Backport 8316108: [Lilliput/JDK21] Cherry-pick: 8305898: Alternative self-forwarding mechanism

Differences with upstream pr 17755:

  1. UseAltGCForwarding condition guards the critical parts of the change
  2. The use of displaced_mark_helper is explained in https://github.com/openjdk/jdk/pull/13779/files#r1305779757
  3. A test fix that only matters in 32-bit x86
  4. Cosmetic changes
