Philip Reames 91a083c57f Carry facts about nullness and undef across GC relocation ... This change implements four basic optimizations: If a relocated value isn't used, it doesn't need to be relocated. If the value being relocated is null, relocation doesn't change that. (Technically, this might be collector specific. I don't know of one which it doesn't work for though.) If the value being relocated is undef, the relocation is meaningless. If the value being relocated was known nonnull, the relocated pointer also isn't null. (Since it points to the same source language object.) I outlined other planned work in comments.
