I had to make a few changes to this patch. I don't like adding
-fchar8_t to lots of non-C++2a tests, so I removed all the lines
adding that to the dg-options. Instead I either ensured all the checks
for char8_t features are guarded by _GLIBCXX_USE_CHAR8_t, or are in
their own new test files that are compiled using -std=gnu++2a.

I also had to fix the changes to
testsuite/util/testsuite_common_types.h because the additions to the
integral types and the atomic integral types were not in the same
order, so testsuite/29_atomics/atomic/requirements/base_classes.cc
failed when using -std=gnu++2a.

I've committed the attached patch.
