* c-cppbuiltin.c (c_cpp_builtins): Bump __cpp_init_captures and __cpp_generic_lambdas for -std=c++2a. Define __cpp_designated_initializers, __cpp_constexpr_in_decltype and __cpp_consteval for -std=c++2a. Remove a FIXME comment about __cpp_concepts for -std=c++2a. * g++.dg/cpp1z/feat-cxx1z.C: Only compile with -std=c++17. * g++.dg/cpp2a/feat-cxx2a.C: Adjust for P1902R1 changes. * g++.dg/cpp2a/desig15.C: New test. * g++.dg/cpp2a/lambda-pack-init3.C: New test. * g++.dg/cpp2a/lambda-generic6.C: New test. * g++.dg/cpp2a/consteval15.C: New test.
