Reflective method lookup for structural type fails if the method has a wider parameter type in the classfile

[Atry]

(see comments below for more reduced examples, the bug is not related to by-name parameters)

def byName(b: => Int): Int = b
def namer[A, B](f: A => B): (A => B) { def apply(i: A): B } = f

val namedFunction = namer(byName _)
namedFunction(1)

This example works in 2.11.11, but the underlying bug also exists in 2.11 (see comments)

[Atry]

The function does not have to be a reflective call, because there is a generic version of apply on Function1.
Scalac should detect if the method refinement has a generic version on base types.
