Instead of storing double in double and then truncating to int, store int in long
and then widen to long long. This preserves test coverage (as these tests are
interested in various tuple conversions) while avoiding truncation warnings.
test/std/utilities/tuple/tuple.tuple/tuple.cnstr/const_pair.pass.cpp
Since we aren't physically truncating anymore, t1 is equal to p0.
test/std/utilities/tuple/tuple.tuple/tuple.cnstr/convert_copy.pass.cpp
One edit is different from the usual pattern. Previously, we were storing
double in double and then converting to A, which has an implicitly converting
constructor from int. Now, we're storing int in int and then converting to A,
avoiding the truncation.
Fixes D27542.

This is a breaking change. The SFINAE required is instantiated the second
the class is instantiated, and this can cause hard SFINAE errors
when applied to references to incomplete types. Ex.
struct IncompleteType;
extern IncompleteType it;
std::tuple<IncompleteType&> t(it); // SFINAE will blow up.

Summary: No declaration for the type `tuple` is given in c++03 or c++98 modes. Mark all tests that use the actual `tuple` type as UNSUPPORTED.
