[PATCH] D122983: [C11/C2x] Change the behavior of the implicit function declaration warning

[Paul Walker via Phabricator via cfe-commits]

paulwalker-arm added a comment.

The tests verify a set of builtins do not exist when the associated feature flag is not present.  They sit within CodeGen because the tests were plentiful and it did not seem worth duplicating them.
