[GROOVY-10076] No warning for type parameter that hides a type

Description

Consider the following:

class Type<T> {
  def <T> m(T t) {
  }
}

In this case, I think it was an accident to add "<T>" to the method declaration.

The method type parameter "T" hides the enclosing class type parameter "T" without warning. I think you could get the same situation with "class T" in the same package. ecj states "The type parameter T is hiding the type T".
