Lazy annotations for DefDef and TypeDef don't get forced until refchecks

```scala
class AnnotNotFound {
  def foo(a: Any) = ()

  foo {
    @inargument
    def foo = 0
    foo
  }

  () => {
    @infunction
    def foo = 0
    ()
  }

  @classs
  class C

  class D[@typeparam T]

  class E(
  	@valueparam x: Any
  )
}
```

The errors for `inargument` and `infunction` are not issued until the other errors are resolved.
