In CL 349614. we removed the early transformation code that was needed to create the implicit CONVIFACE nodes. Because the transformCall function is not called when translating OFUNCINST. So we add in needed CONVIFACE nodes via typecheckaste(). Fixes #48598 Change-Id: If9dc7040cdc38ef2e52fdbb08c840095651426f2 Reviewed-on: https://go-review.googlesource.com/c/go/+/351856 Reviewed-by: Cuong Manh Le <cuong.manhle.vn@gmail.com> Reviewed-by: Dan Scales <danscales@google.com> Trust: Cuong Manh Le <cuong.manhle.vn@gmail.com> Trust: Dan Scales <danscales@google.com> Run-TryBot: Cuong Manh Le <cuong.manhle.vn@gmail.com> TryBot-Result: Go Bot <gobot@golang.org>
