Several libstdc++ test cases have been adjusted to reflect changes introduced by P3074R7 regarding trivial unions. Specifically, the tests for is_constructible, is_destructible, and is_nothrow_destructible now expect a different value when compiling with C++26 or later (indicated by __cpp_trivial_union >= 202502L), as trivial unions are now considered trivially destructible.
