Addresses GB-100
The unique_ptr and shared_ptr constructors taking nullptr_t delegate to a constexpr constructor, and could be constexpr themselves.
[ Resolved in Rapperswil by a motion to directly apply the words from the ballot comment in N3102. ]
Proposed resolution:
In the 20.3.1.3 [unique.ptr.single] synopsis add "constexpr" to unique_ptr(nullptr_t).
In the 20.3.1.4 [unique.ptr.runtime] synopsis add "constexpr" to unique_ptr(nullptr_t).
In the 20.3.2.2 [util.smartptr.shared] synopsis add "constexpr" to shared_ptr(nullptr_t).
