    c++: fix testcases
    
    Only the first dg-error in constexpr-array23.C needs to be xfailed on the 9
    branch.
    
    lambda-pack-init6.C depends on the fix for PR94546; rather than backport
    that as well, let's remove the test.
    
    gcc/testsuite/ChangeLog:
    
            * g++.dg/cpp0x/constexpr-array23.C: Remove xfail.
            * g++.dg/cpp2a/lambda-pack-init6.C: Removed.
