Remove use of constexpr if that failed on the build bots. Original commit message: It's possible for `getCalleeDecl()` to return a null pointer. This was encountered by a user of our downstream compiler. The case involved a DependentScopeDeclRefExpr. Since this seems to only be for a warning diagnostic, I skipped the diagnostic check if it returned null. But mabye there's a different way to fix this.
