Would it be simpler to define < for that case? Or, we could define a custom one to send to the std::map:

struct CompareValID {
  static bool operator<(const ValID &LHS, const ValID &RHS) {
    if (LHS.Kind != RHS.Kind)
      return LHS.Kind < RHS.Kind;
    return LHS < RHS;
  }
};

This was a bug reported a while ago on the old bugzilla: https://bugs.llvm.org/show_bug.cgi?id=46183

• add target requirement to lit test
