src/compiler/ast-graph-builder.cc:1547: VisitForValueOrNull(it->second->setter);
If we ever deoptimize while evaluating the setter then the HomeObject for the
getter won't be set yet, but full-codegen will not set it because the ordering
is different in full-codegen. Not sure if evaluating the FunctionLiteral could
ever cause a deopt though.
