Why did you change this? It now relies on the use order of the projections.

   for (UseIter i = uses().begin(); i != uses().end(); ++i) {
     if ((*i)->opcode() != IrOpcode::kProjection) continue;

-    DCHECK_LT(index, projection_count);
-    DCHECK_EQ(NULL, projections[index]);
-    projections[index] = *i;
+    DCHECK_GE(OpParameter<int32_t>(*i), 0);

   }
