Dan Scales 80783558b0 cmd/compile: make sure imported instantiated types have their methods created ... We should be putting a newly instantiated imported type in Instantiate/doInst onto the instTypeList, so its methods/dictionaries are instantiated. To do this, we needed a more general way to add a type to instTypeList, so add NeedInstType(), analogous to NeedRuntimeType(). This has the extra advantage that now all types created by the type substituter are added to instTypeList without any extra code, which was easy to forget. doInst() now correctly calls NeedInstType(). This is a bit aggressive, since a fully instantiated type in a generic function/method may never be used, if the generic method is never instantiated in the local package. But it should be fairly uncommon for a generic method to mention a fully instantiated type (but it does happen in this bug). Fixes both cases mentioned in the bug.
