Hello Juan Yu, Internal Jenkins,

IMPALA-2643: Prevent migrating incorrectly inferred identity predicates into inline views.

Inferred predicates implicitly referring to the same expr can be migrated into an inline
view where the post-substitution predicate is an identity predicate. If such a predicate
is assigned to an plan node later, it incorrectly drops NULLs.
