This initial design of the C API is different from (and mostly higher level

explicit graph construction APIs for generating infeed enqueue/dequeue
ops (e.g. split_inputs_and_generate_enqueue_ops() and generate_dequeue_op()),
while the C API takes an input graph and redirects all input nodes to feed the
infeed enqueue.

One requirement/restriction is that the input nodes in the TF
graph (e.g. Placeholder) must specify their tensor shapes, for infeed enqueue
and dequeue nodes to properly compile with XLA. The API for more general shape
support will be designed and implemented later.

A. Unique TensorFlower [Sat, 17 Mar 2018 18:21:02 +0000 (11:21 -0700)]
Normally tf2xla (autoclustering, jit_scope and rewrite) rely on graph optimization
passes to outline subgraphs. The XLA device itself only sees Compute() calls for
_XlaLaunch ops. All other ops are registered with a dummy op factory that just
prints an error.

This patch adds an alternative, selected at registration time, that disables
default graph optimization and instead registers a non-dummy op implementation.

This op implementation compiles the op "on demand"; it generates a fake graph containing
_Arg and _Retval nodes and calls into the XlaCompiler code as usual.

This allows the device to be used as a "normal" TensorFlow device, as well as from
Eager mode, at the expense of performance.

Later additions will add the ability to create traces to amortize kernel launch overhead,
and the ability to combine op-by-op/tracing and autoclustering with jit_scope annotations.
