LGTM, but more can be done.

http://codereview.chromium.org/8588027/diff/1/vm/object.cc
File vm/object.cc (right):

http://codereview.chromium.org/8588027/diff/1/vm/object.cc#newcode2062
vm/object.cc:2062: ParameterizedType::New(cls, type_arguments));
This call to ParameterizedType::New happens when instantiating generics at run
time. It should therefore allocate in the new gen. We may want a separate call
if we do not want to allocate all types in the new gen.

http://codereview.chromium.org/8588027/diff/1/vm/object.cc#newcode2265
vm/object.cc:2265: Heap::kOld);
You can also use Heap::kNew here.

http://codereview.chromium.org/8588027/diff/1/vm/object.cc#newcode2504
vm/object.cc:2504: TypeArray& instantiated_array =
TypeArray::Handle(TypeArray::New(num_types));
The same applies here to TypeArray::New as to ParameterizedType::New above.
Either we allocate all types in the new gen, or we provide a separate call to
allocate in the new gen here.

Regis,

Thanks for looking at other objects involved in runtime types. As you said we
should discuss the expected life-time of all type-related objects.
