[llvm] r235219 - Suppressing the C4324 warnings generated by MSVC. This is the only declarative instance that would generate the warning, but it accounted for about 525+ warnings due to template instantiations. This is a marginal-value warning which we may decide to disable more broadly, but since this header is in Support and may be used out of tree, it's a low burden for us to be warning-free in this case.
