Title: Use std::is_trivially_destructible instead of std::has_trivial_destructor

`std::has_trivial_destructor` is from a draft of the standard; the final version uses `std::is_trivially_destructible` instead. GCC 4.8 supports only `std::is_trivially_destructible`. I'm not sure about Clang.

This commit changes `std::has_trivial_destructor` to `std::is_trivially_destructible`. If Clang doesn't support `std::is_trivially_destructible` then I suppose some ifdefs will be needed, but unfortunately I don't have access to Clang to test this.
