Jonathan Wakely ea05497d4a libstdc++: Extend constexpr if to C++14 in _Hashtable::_S_nothrow_move() 
We can use diagnostic pragmas to allow the constexpr if version of this
function to be used for C++14 as well. We still need the __and_ version
for C++11 because we can't use 'if' in constexpr functions at all before
C++14.

Also use the integral_constant::value static data member instead of
invoking integral_constant::operator(), as it's a tiny bit cheaper to
compiler.

libstdc++-v3/ChangeLog:

	* include/bits/hashtable.h (_Hashtable::_S_nothrow_move): Use
	diagnostic pragmas to allow constexpr if in C++14. Use value
	member instead of operator().
