Fix type is_pod trait for GCC 10.2.

[tomilov]

Currently for __GNUC__ == 10 and __GNUC_MINOR__ == 2 second part of condition (__GNUC__ >= 4) && (__GNUC_MINOR__ >= 3) is false. Whole condition expected to be true. For that lexicographical comparison is needed. Something with aid like this.

Currently it is impossible to construct thrust::device_vector<S> from std::vector<S>, when host compiler is g++ from GCC 10.2:

struct S { int i; };
static_assert(std::is_trivially_destructible_v<S>, "!");
std::vector<S> u{S{1}, S{2}, S{3}};
thrust::cuda::vector<S> v{u.cbegin(), u.cend()};

due to wrong SFINAE picking on this line (which in fact must be enable_if_destroy_range_case3) which result in error starting from thrust::cuda::vector<S>::~vector destructor.

Good catch, we should be able to get this in for 1.11.0.

We should also make it clearer in those GPUtester comments that they're coming from a bot :)

All set. Thanks for the patch!
