    [turbofan] Properly implement %_ClassOf intrinsic. · 3e407093
    bmeurer authored
    The %_ClassOf intrinsic roughly corresponds to the deprecated ES5
    [[Class]] internal property, and should not be used anymore ideally.
    However since we still have quite a couple of uses of this intrinsic
    in the self hosted JavaScript builtins, we would tank some builtins
    like Map, Set, WeakMap, WeakSet, etc. quite significantly unless we
    also support this intrinsic until the builtins are all migrated to
    C++/CSA builtins.
