For selector expression "x.M" where "M" is a promoted method, irgen is using the type of receiver "x" for determining the typeparams for instantiation. However, because M is a promoted method, so its associated receiver is not "x", but "x.T" where "T" is the embedded field of "x". That casues a mismatch when converting non-shape types arguments. Fixing it by using the actual receiver which has the method, instead of using the base receiver.
