LOG: [libc++] Avoid warning for large types with std::atomic in the test suite

It is legitimate for the test suite to use types that are slow to use
with std::atomic, since we need coverage for those too. If we don't
disable the warning, it is promoted to an error, which prevents us
from testing such types.
