ae313d4af3 cmd/protoc-gen-go: fix Reset method
The MessageInfo cache, once set, must not be cleared, otherwise
there exists a *messageState value where the MessageInfo value is nil.
Fix the generation of the Reset method to avoid clearing this value.

26aef9d6d6 cmd/protoc-gen-go: add support for field-tracking
Field-tracking is an experimental feature in the Go linker
where it statically tracks whether a Go struct field is used.
This CL modifies the generator to emit special markers that
tells the linker to know which fields to track.
