Summary:
Rehash of https://github.com/pytorch/pytorch/issues/22322 .
Given that python 2.7 will be EOL'd on Jan 1, 2020 and we have models depending on python3.5+, we'd like to update the ROCm CI across the board to python3.6.
This PR adds the skip tests and some semantic changes for PyTorch.
Added pattern match skip for anything but the ROCm CI compared to #223222 for the python find step in the PyTorch build.

Open tasks/questions:
* RoiAlignTest.CheckCPUGPUEqual fails in the Caffe2 unit tests. Is this something expects / can be skipped?
* for testing, I've used update-alternatives on CentOS/Ubuntu to select python == python 3.6. Is this the preferred way?

Summary:
Some of my qpth users have told me that updating to the latest version of PyTorch and replacing the btrifact/btrisolve calls with the LU ones wasn't working and I didn't believe them until I tried it myself :)
These updates have broken unpivoted LU factorizations/solves on CUDA. The LU factorization code used to return the identity permutation when pivoting wasn't used but now returns all zeros as the pivots. This PR reverts it back to return the identity permutation. I've not yet tested this code as I'm having some trouble compiling PyTorch with this and am hitting https://github.com/pytorch/pytorch/issues/21700 and am not sure how to disable that option.
Here's a MWE to reproduce the broken behavior, and my fix.
```python
torch.manual_seed(0)
n = 4
L = torch.randn(n,n)
A = L.mm(L.t()).unsqueeze(0)
b = torch.randn(1, n)
A_lu_cpu = torch.lu(A)
A_lu_cuda_nopivot = torch.lu(A.cuda(), pivot=False)
A_lu_cuda_pivot = torch.lu(A.cuda(), pivot=True)
print('A_lu_cuda_nopivot\n', A_lu_cuda_nopivot)
print('-----\nA_lu_cuda_pivot\n', A_lu_cuda_nopivot)
x_cpu = b.lu_solve(*A_lu_cpu)
x_cuda_nopivot = b.cuda().lu_solve(*A_lu_cuda_nopivot)
x_cuda_nopivot_fixed = b.cuda().lu_solve(
A_lu_cuda_nopivot[0], torch.arange(1, n+1, device='cuda:0').int())
x_cuda_pivot = b.cuda().lu_solve(*A_lu_cuda_pivot)
print(x_cpu, x_cuda_nopivot, x_cuda_nopivot_fixed, x_cuda_pivot)
```
Output:
```

Summary:
This #20919 without the changes to aten/src/THC/THCIntegerDivider.cuh
that broke the ROCm build.
cc bddppq
Original summary:
This fixes advanced indexing in cases where there's more than 2^31-1
bytes in the output. The `gpu_index_kernel` was missing the
`can_use_32bit_indexing`/`with_32bit_indexing` check.
This also adds a number of TORCH_INTERNAL_ASSERTS in Loops.cuh,
OffsetCalculator, and IntDivider that sizes are fit in a signed 32-bit
integer.
More comprehensive tests that require a 32 GB GPU are here:

Summary:
This PR also moves Device::validate into the header file, which makes
statements like `Device d = kCPU` effectively free.
Device includes the device's index, so TensorIterator::compute_types
now implicitly checks that all CUDA inputs are on the same GPU.
Previously, this was done ad-hoc in places like TensorIterator::binary_op.
Note that zero-dim Tensor (scalars) are NOT required to be on the
same device as other inputs because they behave almost like Python numbers.
TensorIterator handles copying zero-dim Tensors to the common device.
Prior to this PR, TensorIterator would copy zero-dim Tensors between CPU
and GPU, but not between different GPUs (because Backend didn't encode
the GPU index). This removes that restriction.

Summary:
Copy.cu goes from 308 to 190 lines of code. In general it uses, the same
copy strategy, using cudaMempcyAsync, a pointwise kernel, or a copy
using temporary buffers. The pointwise kernel has slightly improved
performance when broadcasting due to faster index calculation.
This deletes "`s_copy_`", "`_s_copy_from`", and "`_copy_same_type_`". The only
entry-point now is "`copy_`".
A mini-benchmark is here:

After:
https://gist.github.com/colesbury/9024d242b56ab09a9ec985fa6d1620bc
Results were measured on 2.2 GHz Broadwell; no-turbo; one thread;
compiled with GCC 7.3.0. (Results are slower than typical usage due to
turbo being off.)
The only significant differences is in the CUDA [1024] -> [1024, 1024]
broadcasting copy which is ~25% faster. I don't expect a noticeable
difference in real programs.
CPU copy overhead is a tiny bit (~200 ns) faster, but I don't expect
anyone to notice that.

* **#18598 Turn on F401: Unused import warning.**
This was requested by someone at Facebook; this lint is turned
on for Facebook by default. "Sure, why not."
I had to noqa a number of imports in __init__. Hypothetically
we're supposed to use __all__ in this case, but I was too lazy
to fix it. Left for future work.
Be careful! flake8-2 and flake8-3 behave differently with
respect to import resolution for # type: comments. flake8-3 will
report an import unused; flake8-2 will not. For now, I just
noqa'd all these sites.
All the changes were done by hand.

Stack:
* #17926 Implement at::has_internal_overlap helper function
* **#17927 Error out on in-place (unary) ops on tensors that have internal overlap**
On the way to #17935.
Works for CPU and CUDA on the following ops:
- abs_, acos_, asin_, atan_, ceil_, cos_, erf_, erfc_, exp_, expm1_
- floor_, log_, log10_, log1p_, log2_, round_, rsqrt_,
- sin_, sqrt_, tan_, tanh_, trunc_
This PR adds a check to see if the out/result tensor has internal
overlap. If it does, then we error out because the result **may** be
incorrect.
This is overly conservative; there are some cases where if the result is
the same as the input, the inplace operation is OK (such as floor_,
round_, and trunc_). However, the current code isn't organized in such a
way that this is easy to check, so enabling those will come in the future.

This PR causes kthvalue to be consistent with sort
(i.e. treat NaN as larger than any number), so that
`a.kthvalue(n) == a.sort()[n - 1]`.
One drawback is that median with a NaN argument does not return NaN,
which is a deviation from NumPy.
