[PATCH] D66822: Hardware cache line size builtins

[Zoe Carver via Phabricator via cfe-commits]

zoecarver added a comment.

It may be a good idea only to enable this when `-march=native`. And _maybe_ remove the constexpr requirement (though it would make this feature significantly less useful it would also make it significantly more accurate).
