Allow non-nullable usage to imply non-null intent.

If a method parameter is used in unconditional control flow in a way
that a `null` value would directly lead to an exception (i.e. by
dereferencing it, or by passing it to a method that requires a
non-nullable value), this is treated as implying that the method
parameter is intended to be non-nullable.
