reflect, runtime: replace reflect.typelinks to return types, not offsets

Change reflect to call a new function to get the compiled type descriptors,
returning the type pointers directly rather than the type offsets.

We have to keep the existing reflect.typelinks for third party
packages that break the rules and call it directly using linkname.
