More warnings with CUDA 11.8 and GCC 11.3.0

[lahwaacz]

I'm getting a couple of warnings on the current develop branch:

/build/ginkgo-hpc-git/src/ginkgo/cuda/base/pointer_mode_guard.hpp: In destructor ‘gko::kernels::cuda::cublas::pointer_mode_guard::~pointer_mode_guard()’:
/build/ginkgo-hpc-git/src/ginkgo/cuda/base/pointer_mode_guard.hpp:82:10: warning: ‘bool std::uncaught_exception()’ is deprecated: use 'std::uncaught_exceptions()' instead [-Wdeprecated-declarations]
   82 |         if (std::uncaught_exception()) {

  109 |   bool uncaught_exception() _GLIBCXX_USE_NOEXCEPT __attribute__ ((__pure__));
      | ^ ~~~~~~~~~~~~~~~~

(the same appears on a few more places in pointer_mode_guard.hpp)

/build/ginkgo-hpc-git/src/ginkgo/cuda/test/base/index_set.cu(84): warning #177-D: function "<unnamed>::index_set::assert_equal_arrays" was declared but never referenced

From doxygen 1.9.5:

warning: Tag 'CLASS_DIAGRAMS' at line 85 of file '/build/ginkgo-hpc-git/src/build/doc/Doxyfile-usr' has become obsolete.
         To avoid this warning please remove this line from your configuration file or upgrade it using "doxygen -u"

Thanks for the report! We can't do anything about the unhandled_exception warning without requiring C++17 support or some hacky workarounds that I'd like to avoid. The assertion failures are tracked with #1143, the rest should be fixed by #1189
