c++: mark_single_function and SFINAE [PR108282]
We typically ignore mark_used failure when in a non-SFINAE context for
sake of better error recovery. But in mark_single_function we're
instead ignoring mark_used failure in a SFINAE context, which ends up
causing the second static_assert here to incorrectly fail.
PR c++/108282
gcc/cp/ChangeLog:
* decl2.cc (mark_single_function): Ignore mark_used failure
only in a non-SFINAE context rather than in a SFINAE one.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/concepts-requires34.C: New test.
