tcg: Use HAVE_CMPXCHG128 instead of CONFIG_CMPXCHG128 We adjust CONFIG_ATOMIC128 and CONFIG_CMPXCHG128 with CONFIG_ATOMIC128_OPT in atomic128.h. It is difficult to tell when those changes have been applied with the ifdef we must use with CONFIG_CMPXCHG128. So instead use HAVE_CMPXCHG128, which triggers -Werror-undef when the proper header has not been included. Improves tcg_gen_atomic_cmpxchg_i128 for s390x host, which requires CONFIG_ATOMIC128_OPT. Without this we fall back to EXCP_ATOMIC to single-step 128-bit atomics, which is slow enough to cause some tests to time out.
