068815c2 - [cxx-interop] Remove some duplicated lookups

[cxx-interop] Remove some duplicated lookups Repeatedly lookup up a key from a dictionary can be justified whenever the content of the dictionary might change between the lookups (so any references into the dictionary might get invalidated). We had a couple of instances where as far as I can tell no such modifications should happen between two lookups with identical keys. This PR simplifies the code to remove the extra lookups. It also removes a dictionary that was completely unused.
