Subject: [PATCH] c++: add fixed test [PR94231]

I was suprised to find out that r14-8759 fixed this accepts-invalid.

clang version 17.0.6 rejects the test as well; clang version 19.0.0git
crashes for which I opened
<https://github.com/llvm/llvm-project/issues/80869>.

	PR c++/94231

gcc/testsuite/ChangeLog:

	* g++.dg/cpp0x/deleted17.C: New test.
