[tf2xla] Introduce XlaTensorInfo
XlaTensorInfo is side-band data for Tensors. It can be used to store
information about Tensors that is not possible to store in the Tensor
itself. The XlaTensorInfos are managed by XlaTensorInfoManager, which
is an Allocator, which allows it to release the TensorInfos when the
underlying Tensor is released. Looking up an XlaTensorInfo for a
Tensor requires a hash table lookup. This implementation keeps this
off the fast path and only looks the tensorinfos up when they are

Remove nsync header files from tensorflow/core/platform/default/mutex.h
The implementation of tensorflow/core/platform/default/mutex.h uses the nsync
library, so mutex.h has included nsync header files.
This has been awkward, because each TensorFlow build (bazel, cmake, make, plus
the instructions for compiling individual custom ops, on all the various
platforms) has needed to handle the include paths correctly, reaching into a
package that is downloaded separately from TensorFlow itself.
This change avoids that awkwardness, instead taking on two different
irritations:
- mutex.h now defines two structs that are large enough and aligned enough to
contain an nsync_mu and an nsync_cv. This is an abstraction violation,
because TensorFlow's source should not need to know how big these data
structures are. However, this is unlikely to cause problems because:
1) this is checked by a static assertion in mutex.cc, so we will notice
immediately should a change be needed, and
2) this will likely never fail because we have no intent of allowing nsync's
data strcutures to get bigger.
- The methods of mutex and condition_variable can no longer be inlined, because
that too would require mutex.h to include the nsync header files. (Or we'd
need to declare the nsync functions directly in mutex.h, which would be
another abstraction violation.) However, this is a small imposition
because the overhead of a procedure call is typically small.
The assumption behind this CL is that these irritations are less important than
the ongoing frustration of maintaining the complex include path in multiple build
systems.

Include test_ops_kernels in main TF build rule.
We already include the test_ops Python library. Without the
corresponding C++ library, these ops can't be created with the C API
enabled.

Add ScopedAllocator and ScopedAllocatorMgr.
A ScopedAllocator is a new memory allocator which manages slices of a large
tensor. ScopedAllocatorMgr manages all scoped allocators per device. The
ScopedAllocatorMgr comprises of multiple ScopedAllocatorContainers, one per
step id. If a step terminates abnormally, the corresponding
ScopedAllocatorContainer will clean up all allocated memory in that step.

Add a GatherExpander pass that can rewrite Gather ops back into HLO soup
With this pass we now have a minimal viable implementation of gather on all
platforms. The code is a bit gnarly but conceptually this is very similar to
what we do in the tf2xla bridge today.
