In order to make sure we export the dictionaries/shape methods for all
fully-instantiated types in inlineable functions, we need to descend
fully into types. For example, we may have a map type (e.g.
map[transactionID]Promise[*ByteBuffer]), where the key or value is a new
fully-instantiated type. So, I add a new checkFullyInst() traversal
function, which traverses all encountered types, but maintains a map, so
it only traverse it type once. We need to descend fully into interfaces,
structs, and methods, since a fully-instantiated type make occur in any
fields or arguments/results of methods, etc.
