* include/bits/stl_pair.h (__may_be_null_pointer_init): New.
(pair::pair): Eliminate the redundant pair(U1&&, U2&&) constructor.
Add lvalue pair<U1, U2> constructor to handle non-const pair lvalues.
Remove the old variadic constructor, and instead provide several
variadic constructors that avoid failing when attempting to
initialize a pointer from a null pointer constant.
* testsuite/20_util/pair/moveable.cc (test3): Add new tests with
initialization of pointers from the null pointer constant.
