    x86-64: Check CMPXCHG16B for x86-64-v[234]
    
    x86-64-v2 includes CMPXCHG16B.  Since -mcx16 enables CMPXCHG16B and
    defines __GCC_HAVE_SYNC_COMPARE_AND_SWAP_16, check it in x86-64-v[234]
    tests.
    
            PR target/97250
            * gcc.target/i386/x86-64-v2.c: Verify that
            __GCC_HAVE_SYNC_COMPARE_AND_SWAP_16 is defined.
            * gcc.target/i386/x86-64-v3.c: Likewise.
            * gcc.target/i386/x86-64-v4.c: Likewise.
