This op doesn't care about the type of the inputs, so add it to the
quanitization support whitelist.
This partially addresses #20955 (Cast is still unsupported)

This change returns NaN as the maximum error if any gradient
entry is NaN. This avoids masking gradient implementation
errors in tests that don't expect to see NaN results.

Escaping the transitive dependency on :compilation_passes is impossible:
//tensorflow/compiler/jit:deadness_analysis_test
-> //tensorflow/compiler/jit/kernels:xla_launch_op
-> //tensorflow/compiler/jit:xla_device
-> //tensorflow/compiler/jit:jit_compilation_passes
-> //tensorflow/compiler/jit:compilation_passes
Linking both :compilation_passes and :deadness_analysis_internal into one test
leads to ODR conflicts. Asan complains about them. Just remove the internal
target and add the internal header to the test.

This fix tries to address the issue raised in 21380
where the gradient of tf.nn.relu6 throws out an error.
The issue seems to be that relu6 was not placed
in OpDoesntRequireInput like tf.nn.relu.
This fix fixes 21380.

otherwise the results are under-constrained/undefined.

Dataset.list_files() matches no files.
The main effect of this change is to change a late `OutOfRangeError` at iteration time into an earlier `InvalidArgumentError` at initialization time, which will improve error reporting in Eager mode and high-level APIs that control the training loop (Estimator, Keras, etc.). This change will break some advanced uses that concatenate many potentially empty file listings, but it is possible to work around this using `tf.data.Dataset.from_tensor_slices(tf.matching_files(file_pattern))`. We expect that the improved productivity from an earlier, more actionable error message will outweigh the inconvenience of modifying a small number of existing programs.

The old code ensured that failed sub-streams would not be re-used, but
had two flaws:
1) It only checked for failed sub-streams during Return.
2) It didn't actually remove the failed sub-streams from our state.
The new code fixes these two flaws, and adds an extra test that
explains why (1) is insufficient.

As a follow-on cleanup for cl/206980796 ("Overhaul XLA:CPU's calling
convention.") I want to introduce a BufferInfo class that encapsulates whether a
buffer is a constant, an entry parameter or a temp without using the fragile
"size < 0" scheme I have today. To do this efficiently I need a place to put
the BufferInfo class that will be visible to MallocContiguousBuffers. Instead
of creating (what seemed to me) an odd layering with BufferInfo in aot/runtime.h
I decided to pull in the runtime into xla_compiled_cpu_function since that's the
only user.

5624727 cycles (100.% 100?) :: 3865.8 usec [...] TOTAL
2121832 cycles (37.72% 38?) :: 1458.3 usec
1932379 cycles (34.36% 72?) :: 1328.1 usec
264366 cycles ( 4.70% 77?) :: 181.7 usec
The first line with the total is a little wird, but I figured it was
better to do it this way than to waste a precious character of
horizontal space.
I also considered rendering it as e.g. "?38%". This is slightly more
expressive, but it gets hard to read pretty fast with two characters
smushed against both of the numbers.
I put the sigma at the end because I find it easier to read: With the
sigma at the beginning, its tips often blend in with the first number;
e.g. I find "?77" less readable than "77?".
Similarly I considered displaying more than two significant figures in
the percent, but since it's cumulative *anyway*, I didn't think these
were relevant.
This formatting is somewhat inconsistent with how we do the categories
tables:
258 ( 6.68% ?87.81%) non-fusion elementwise (12 ops)
I can change these to match if we want, but I sort of think of them as a
different case. The categories tables have a lot more whitespace in
between entries (namely, one line per instruction in the category), so
noisiness is not nearly as significant a concern.
