1064. Defaulted move constructor for a union

[Voted into the WP at the November, 2010 meeting.]

The new wording in 11.4.5.3 [class.copy.ctor] specifies the behavior of an implicitly-defined copy constructor for a non-union class (paragraph 16), an implicitly-defined move constructor for a non-union class (paragraph 17), and an implicitly-defined copy constructor for a union (paragraph 18), but not an implicitly-defined move constructor for a union.

Proposed resolution (August, 2010):

This issue is resolved by the resolution of issue 1051.
