[Bug c++/43167] Warnings should not be disabled when instantiating templates defined in system headers

ICC doesn't warn (emits another spurious warning, by the way, which has nothing
to do with this issue). More generally, compilers using the EDG front-end, eg,
Comeau, apparently do not warn at the most strict diagnostic level. Likewise
SunStudio. I'm not saying we cannot do better, just, seems a pretty
sophisticated goal, and really, in my opinion, we should be *very* careful with
false positive, because normally it's unacceptable to emit warnings about
internal details of the implementation.
