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

[serge via Phabricator via cfe-commits]

serge-sans-paille added a comment.

- Be less intrusive in the getBuiltinID() system, just hook inside CGExpr.cpp
- Take into account @george.burgess.iv remark on builtins referencing themselves in an override. Add a test case for that scenario.
