5a3ea746 - Remove unused initializer from GraphProto as well as name_to_initial_tensor_ in CleanUnusedInitializers. (#2320)

Remove unused initializer from GraphProto as well as name_to_initial_tensor_ in CleanUnusedInitializers. (#2320) * Remove unused initializer from GraphProto as well as name_to_initial_tensor_ in CleanupUnusedInitializers. This means initializers that have been replaced during graph optimizations are not left in the GraphProto when we save an optimized model. * Handle edge case where a model has an unused initializer with matching graph input by also removing the graph input. * Use non-const iterators in std::find_if calls to make centos build happy.
