The old code was using VariableMode, but that signal is both over-pessimistic (some CONST and LET variables need no hole-initialization) and inconsistent with other uses of the InitializationFlag enum (such as %LoadLookupSlot). This changes no observable behavior, but removes unnecessary hole initialization and hole checks in a few places, including block-scoped function declarations, super property lookups, and new.target.
