[PATCH] D71082: Allow system header to provide their own implementation of some builtin

I'd prefer not to revert a change that's three months old without some sort of evidence the issue is actually the compiler's fault.  If nobody else has seen an issue, it's probably okay to let it sit for a day or two.
