9471fabf - [clang] Fix issues with const/pure on varargs function. (#190252)

[clang] Fix issues with const/pure on varargs function. (#190252) There are two related issues here. On the declaration/definition side, we need to make sure the markings are conservative. Then on the caller side, we need to make sure we don't access parameters that don't exist. Fixes #187535.
