MDEV-7398 mysqld segfaults on FreeBSD 10.1 i386 when built with clang 3.4
in cmake tests let's treat clang like gcc (same options, same builtins) in many cases. * don't check the compiler when * testing for -fvisibility=hidden support * testing for HAVE_ABI_CXA_DEMANGLE * testing for HAVE_GCC_ATOMIC_BUILTINS * when removing options with string(replace) * when running ${CC} --version (ignore the error instead) * run ABI checks for clang * use "canonical" gcc flags for clang * fix groonga too Also: * add cmake detection for gcc __atomic_* builtins. they might be supported (__ATOMIC_SEQ_CST is defined), but not for all operand sizes. In particular, 64-bit atomic load is problematic on i386 * cache check results for Windows * remove the test for HAVE_CXXABI_H (HAVE_ABI_CXA_DEMANGLE is suffifient)
