* Update CMakeLists.txt
Add 128bit int support if using nvc++ to solve #310
@jeffhammond, would you please give it a try?
* Update CMakeLists.txt
correct copy paste error
* Fixed template struct/class mismatch
* Use platform implementation instead of std::abs and std::conditional during nvrtc compilation
* Use platform implementation instead of std::abs and std::conditional during nvrtc compilation
* Revert absolute_value() usage
`CUDA_PERROR_EXIT ` can lead to incorrect usage (see e.g. [this description](https://www.cs.technion.ac.il/users/yechiel/c++-faq/macros-with-if.html)) because it contains an incomplete `if` expression. Consider:
```
if (condition)
CUDA_PERROR_EXIT(cudaFree(x))
else
free(x);
```
The author of the code forgot to add a semicolon after the macro. In that case, the `else` will bind to the `if` inside the macro definition, leading to code that the author did not intend or expect. It the author does use a semicolon, the code will not compile, which is awkward.
The change adds a `do while` around the `if`, which always requires a semicolon.
This PR also adds the text of the failing expression to the printed error message.

When split-k is enabled, we should set alpha to 1 and beta to 0 for the
split-k gemm kernel.
The fix was from hwu36. I only did fixed some minor typos along with his
fix.
* Fix separate compilation `-dc`
- when cutlass is included in multiple compilation units
compiled with `-dc` OOB_NAN_F16x8 device constant is
instantiated multiple times causing
Multiple definition of '_ZN7cutlass4arch13OOB_NAN_F16x8E' error
This PR makes this variable a local constant as it is not
modified during runtime
