Crash when expanding over std::tuple

[katzdm]

#include <tuple>


int main() {
  std::tuple<int, bool, char> t;
  template for (auto e : t);
}

Not exactly sure how I missed that one lol

Lol this works on godbolt now: https://godbolt.org/z/Gn3r1caxM

But still fails an assertion in CodeGen when built with assertions. Will keep this open for now.
