[XLA] Assert that all buffers and sub-buffers passed to XLA have an explicit pointer.

In the past, we allowed sub-buffers to be null if the top-level tuple
was non-null.

This doesn't actually work well on the GPU: For ops that are implemented
using cudnn or cublas, we have to have a pointer to the sub-buffer on
the host in order to make the call.  Retrieving it from the GPU in an
efficient manner is complicated, and the best we can come up with isn't
all that efficient (fundamentally having to pull data down from the GPU
blocks the ability of the CPU to "run ahead" of the GPU).

Since TF wasn't making use of our flexibility *anyway*, we add the
requirement that XLA be given non-null pointers to all sub-buffers.
