[PATCH] D26458: Protect nested-exceptions tests under no-exceptions

[Asiri Rathnayake via cfe-commits]

rmaprath added a comment.

Not sure if either of these tests add much value to the no-exceptions variant, using `std::nested_exception` with such a library seem pointless to me. Perhaps marking these as `UNSUPPORTED` is a better fix?
