@cherrymui requested issue #44586 to be considered for backport to the next 1.16 minor release.

@gopherbot please backport this to Go 1.16. This is a regression causing runtime crash without easy workaround.

…ace when dynlink

When using plugins, a type (whose value) may be pass to a plugin
and get converted to interface there, or vice versa. We need to
treat the type as potentially converted to interface, and retain
its methods.

Updates #44586.
Fixes #44638.
