The compiler was confused when inlining a T.Method(f()) call where f returns multiple values: support for this was marked as TODO. Variadic calls are not supported but are not inlined either. Add a test preventively for that case. Fixes #4167. R=golang-dev, rsc, lvd CC=golang-dev https://golang.org/cl/6871043
