Ah yes, because throw_with_nested still depends on atomics in gcc-6-branch, and
so we need a dg-require- in the test (but only on the branch). I'll add that.

I should probably mention that the test passes on trunk in the same
configurations.

Hi Jonathan,

Since you backported this to the gcc-6-branch, I've noticed that the new test
(79114.cc) fails on old ARM versions (eg. when using -march=armv5t).

The error message is:
gccsrc/libstdc++-v3/testsuite/18_support/nested_exception/79114.cc:25: error:
'throw_with_nested' is not a member of 'std'
