Minor changes to reduce diffs between this and a copy we're about to branch.

- InferredType.uninitializationLabel() has never been used, so this is a good opportunity to eliminate it, as well as the createUninitializedType / createNonUninitializedType split in factory methods.
- Most APIs don't need to be public.
- The branched copy will be in a package with @CheckReturnValue enabled, so it needs @CanIgnoreReturnValue on its pop(...) methods. For consistency, I've made this original copy @CheckReturnValue, too.
- Some methods are `private final`, which is redundant. This is as good a time as any to remove `final`.
- I moved a comment to another line so that it doesn't wrap awkwardly in the branched copy, which is a nested class.
