[PATCH] D67968: [TableGen] Introduce a generic automaton (DFA) backend

[James Molloy via llvm-commits]

Wow, that's a really nice builder!

I think I see what's going on; I'm using std::next() eagerly to attempt to
get a correct iterator that isn't invalidated during the loop. But if that
actually ends up being Heads.end(), that *will* be invalidated during
push_back.

I'll fix forward if that's OK?
