cc2e93cff0
Fixes a small omission in libcxx that prevents libcxx being built when -DLIBCXX_ENABLE_EXCEPTIONS=0 is specified. This patch adds XFAILS to all those tests that are currently failing on the new -fno-exceptions library variant. Follow-up patches will update the tests (progressively) to cope with the new library variant.
