      [parser] Change how catch is parsed · a5f559c3
      Toon Verwaest authored
      - Directly declares the special catch variable from the parser-base.
      - Tracks Scope on PreParserBlock and finds conflicting lexical declarations by
        simply walking the VariableMap of the block inserted for the pattern; or the
        catch variable in case of identifier.
      - This also enables throwing errors for duplicate let in the preparser. We may
        have to back that out if it breaks something.
