Just skip the handle creation here and call get on
bytecode_array()->constant_pool() directly ?

Most excellent point, dunno why I didn't see that before. Done.

-  return FixedArray::get(constants, GetIndexOperand(operand_index));
+  return FixedArray::get(*constants, GetIndexOperand(operand_index),
+                         constants->GetIsolate());
