proposal: reflect: allow to create methods for structs at runtime

[audathuynh]

Currently, we can create a struct with embedded fields at runtime.
However, we cannot create methods for structs at runtime.

Below is the statement on the website of Go (https://golang.org/pkg/reflect/#StructOf).
"StructOf currently does not generate wrapper methods for embedded fields. This limitation may be lifted in a future version."

In practice, we may need to create a struct instance to implement the methods of some interfaces.
I would recommend that this feature should be implemented in Go.

What version of Go are you using (go version)?

1.8.3

Generating those wrappers is #15924
Creating and attaching methods at runtime is #16522
