[libcxx] No `struct __is_pod`/`struct __is_empty` in type_traits?

It seems that `struct __is_pod`/`struct __is_empty` does not exist
in any version of libcxx. Is this correct?

(I want to make this confirmed to write a patch for Boost.TypeTraits
to use clang's intrinsics safely with libcxx.)

This is correct. These are clang intrinsics.
