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.

* 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.
