Instantiate and InstantiateLazy have the same signature; on first principles, if Instantiate should work for importers it should be possible to consolidate these APIs. This CL does this. In order to make it work, a typMap needs to be threaded through type expansion to prevent infinite recursion in the case that the Checker is nil. Notably, Named types now must be expanded before returning from Underlying(). This makes Underlying generally unsafe to call while type checking a package, so a helper function safeUnderlying is added to provide the previous behavior. This is probably overly conservative at most call sites, but cleanup is deferred to a later CL.
