    X87: Use Variable::binding_needs_init() to determine hole initialization. · 759a06fc
    zhengxing.li authored
      port 6768456d (r38395)
    
      original commit message:
      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.
