Passing Type[T] implicit argument where T <: AnyRef gives Dotty internal error

[fhackett]

import quoted._

def fn[T : Type](v : T) = ???

Calling:

> fn("foo")
> fn((1,2))
> object O
  fn(O)

etc... (likely for any Ref type)

Give the following error:

Calling foo(1), foo('1') (it seems for any Val type) instead gives the expected "missing implementation" error.
