The semantics of this function is "replace first value input and remove all
other value inputs". I think the current name is a bit misleading. Unfortunately
I don't have a better suggestion right now. But could we at least separate it
out of this block (i.e. move to line 91) and add a comment describing the
semantics?

Done.

   static void ReplaceContextInput(Node* node, Node* context);
   static void ReplaceControlInput(Node* node, Node* control);
   static void ReplaceEffectInput(Node* node, Node* effect, int index = 0);
