Interface methods on generic types require an instantiating stub which the current devirtualization code doesn't provide.

This is just a perf issue, not a correctness issue.

Do not devirtualize shared default interface methods
8f3ebe1 
The result of the devirtualization for a method on a generic type should be an instantiating stub, but this doesn't seem to work right.

Fixing that is a perf issue (that can be triaged/punted - #15977). This commit is a correctness fix to avoid bad codegen for that case.

Resolves #15591.
