Check that the type of an implicitly dereferenced tensor matches the expected input type.
The dtype of a tensor reference can change between the point when it is "produced" by an
operation and consumed by the next operation. This evades checks in the executor that the
type of tensor on each edge matches the type signatures of the producing and consuming operation, which could lead to undefined behavior. Although there is no existing operation that changes the type of a tensor reference, it is possible to use the OpKernelContext API to do so, so we add a further check in the runtime to defend against operations that might be added in the future.

Add functionality to fold batch norm (supporting both fused and unfused batch norm) to support quantized training. The weights are always now scaled by gamma/sigma, where sigma is the moving standard deviation for stability prior to quantization. For improved performance, the moving means and variances are frozen and the training graph modified accordingly.
An additional parameter freeze_batch_norm_delay is added to foldbatchnorm function to set the delay at which training switches from regular batch norm to frozen mean and variances.
Remove placement options within FoldBatchNorm as this causes folded training to place all ops on a single GPU. The modification now significantly speeds up distributed training.

[XLA] Initialize linear indices used by NearComparator.
In unoptimized builds, we'd see miscompares with insanely large indices when
comparing literals containing NaN.
The linear indices may never be updated/initialized if the value NaN was
compared, since:
(NaN > x) == false
(NaN < x) == false
Adds a few tests that were used when debugging, but not a perfect one for this
case. It's currently not possible to test that LiteralTestUtil::Near() fails
when given bad input since it uses the EXPECT_* family of macros, which would
cause the intentional miscompares to fail the test no matter what.

Tolerate Const nodes with no data or with smaller data than is required
by their shape, by zero-extending the Const data to the required size.
We wanted to generate an error on that, but too many
existing graphs already rely on current lax behavior.

Increfing tapes when keeping them around calls to python API functions.
These calls can trigger GIL releases or python GC which can trigger
a change to the set of live tapes and segmentation faults.
