adamk 6768456db5 Use Variable::binding_needs_init() to determine hole initialization
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.
