[PATCH] D39953: [CodeGen] Do not lookup for cached TBAA metadata nodes twice

[John McCall via Phabricator via cfe-commits]

I think having a primary function that handles the caching logic makes some sense.  I think there might be some cases that intentionally don't cache their normal result, though, so it might be harder than you think.  Up to you whether you want to continue.
