tensorflow: Many operations don't support uint64

System information

• Have I written custom code (as opposed to using a stock example script provided in TensorFlow): No
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Mac OS 10.14.2
• TensorFlow installed from (source or binary): binary
• TensorFlow version (use command below): b’unknown’ 1.13.0-rc1
• Python version: Python 3.7.2
• Bazel version (if compiling from source): N/A
• GCC/Compiler version (if compiling from source): N/A
• CUDA/cuDNN version: N/A
• GPU model and memory: N/A

Describe the current behavior

I’ve encountered several operations that support int64 but not uint64, without any clear reasoning. tf.equal, tf.fill, tf.where, and tf.stack, for example, give errors like:

InvalidArgumentError (see above for traceback): No OpKernel was registered to support Op 'Pack' used by node stack (defined at <stdin>:4) with these attrs: [T=DT_UINT64, axis=0, N=2]

Describe the expected behavior

Functions that work for int64s should also work for uint64s when the behavior would be the same.
