Don't add branch prediction hints when compiling under nvcc.

Introduce an "indexed array" analysis
Context: we want to optimize computations hanging off of a embedding lookup from
a constant array. For instance, consider:
embedding = gather from a constant array using non-constant indices
embedding_reshaped = reshape embedding
embedding_reshaped_transposed = transpose embedding_reshaped
result = dot(embedding_reshaped_transposed, constant)
In the graph above, depending on how the details work out, we may be able to
fold `result` into a gather from a precomputed constant array. However, it is
inconvenient to get there by incremental rewrites -- it is probably not
profitable to rewrite embedding_reshaped or embedding_reshaped_transposed [0] as
embedding lookups but we get to "see" that the dot can be rewritten only after
rewriting the reshape and the transpose.
This analysis aims to make the optimization above more straightforward by
allowing a transformation pass (that uses this analysis) to query the analysis
to see if if `result` _can_ be represented as an embedding lookup. If yes it
can then apply some profitability heuristics to decide if it is worth it to
rewrite it as one. This suggested workflow gives us separation of concerns (the
legality of the rewrite is computed separately from its profitability) and, more
importantly, lets us "look ahead" and analyze the dot without rewriting its
operands.
The implementation is far from complete (most of the interesting bits are TODO)
but I wanted to get an early design review before I spent too much time on this.
[0] Under the assumption that transposing or reshaping are not expensive enough
to pay the price of keeping around a new potentially large constant (in
particular, some of these may have been equivalent to free bitcasts).

Fix alignment crashes in AVX512 builds (#19121)
* Fix issue #15588 by simplifying the code
The allocator.h code tried to be clever and use 32 byte alignment for SSE/AVX2/etc use,
and 64 byte alignment for AVX512.
Unfortunately, the #ifdef in use (from EIGEN) is not useful; the bazel BUILD files do
not propagate the tf_copts() compiler flags when the allocator.cc/allocator.h files get
compiled, to EIGEN does not see the actual AVX512 using compiler flags...
Rather than changing compiler flag propagation throughout a whole bunch of code,
there's an opportunity to just simplify the code and always use 64 byte alignment.
Yes it wastes a bit of space, but on the other hand now these allocations are
cache line aligned which isn't a bad thing... and an ifdef can be dropped

* Set EIGEN_MAX_ALIGN_BYTES=64
This patch sets a 64 byte upper bound on the alignment of memory allocated by
eigen. This is necessary to prevent crashes during the execution of the unit
tests when they are compiled with AVX512 support.

* Update the tensorflow/compiler/aot tests for 64 byte alignment
Modifications to the tensorflow/core/framework/allocator.h to always
use 64 byte alignment causes failures in the tensorflow/compiler/aot
unit tests. This patch updates these tests so that they pass with
64 byte aligned allocated memory.

* Update Tensor.Slice_Basic for 64 byte alignment
The test case
//tensorflow/core:framework_tensor_test:Tensor.Slice_Basic
fails with EIGEN_MAX_ALIGN_BYTES set to 64. The reason is that the
slices it takes of the sample tensor are 32 byte and not 64 byte
aligned. This commit increases one of the dimensions of the original
tensor to ensure that the slices taken by the test cases are indeed 64
byte aligned.

* Update ScopedAllocatorConcatOpTest.Reshape for 64 byte alignment
The ScopedAllocatorConcatOpTest.Reshape test requires that the elements
of the field_shapes parameter of ExecOp are multiples of
Allocator::kAllocatorAlignment in size. If they are not, the backing
tensor allocated by PrepOp will have too many elements and reshaping
will fail. This commit modifies the test case, making the elements
64 bytes in size, the new value for Allocator::kAllocatorAlignment.

Improvements to function._FuncGraph.
* Adds 'inputs', 'outputs', and 'name' field to _FuncGraph. This
allows _FuncGraph to encapsulate all the information needed to
convert it to a FunctionDef.
* Refactor logic for converting a Python callable to a _FuncGraph into
a new method, func_graph_from_py_func().
These changes are in preparation for converting tf.cond to emit an If
op. By exposing _FuncGraph functionality outside of _DefinedFunction,
_FuncGraphs can be used to represent functions that are manipulated
(e.g. to output intermediate tensors) before being converted to
FunctionDef protos.

[XLA] Adds HloLivenessAnalysis and HloModuleDCE.
HloLivenessAnalysis marks all live instruction outputs (i.e. tuple elements) for all instructions in an HloModule, propagating live values across computation boundaries.
HloModuleDCE sweeps through each instructions dead tuple elements, eliminating dead code (currently removes dead tuple elements from while loops, but could be extended to do the same for call instructions).

Update SessionTest.testFeedShapeCompatibility to work with C API enabled.
This test got lost in the transition. Prior to enabling the C API,
some constant node whose values were used for shape inference would be
marked as unfeedable in tensor_util.constant_value
(https://github.com/tensorflow/tensorflow/blob/r1.8/tensorflow/python/framework/tensor_util.py#L810).
This shape inference path is no longer used with the C API enabled, so
the constant node is successfully fed, triggering a runtime shape error.
This is arguably a regression, but given that the Python code wouldn't
mark all nodes evaluated during shape inference as unfeedable, it
seems ok to relax the check a little more.
