src/hydrogen.h:1981: return map_->instance_type() == JS_ARRAY_TYPE &&
We didn't do a lookup because that would find native accessors. What
HObjectAccess should we check? How would we build that one? It would
essentially do the same thing: check whether the map is JS_ARRAY and
whether the name of the property is "length". It's a special property,
just like string-length...

I don't think we want to rely on the name here. Shouldn't we better
check the
ObjectAccess instead?
