go/types: if base type for an alias is known, use it when needed Because methods are type-checked before the receiver base type is "complete" (i.e., they are checked as part of the receiver base type), situations occur where aliases of those base types are used (in those methods) but the alias types are not known yet (even though their base types are known). This fix is a temporary work-around that looks syntactically for the base types of alias types and uses those base types when we refer to an "incomplete" alias type. The work-around is completely localized and guarded with a flag so it can be disabled at short notice. The correct fix (slated for 1.12) is to decouple type-checking of methods from their receiver base types. See issue #26854. Fixes #26390.
