Antonio Sanchez 45e67a6fda Use reinterpret_cast on GPU for bit_cast. 
This seems to be the recommended approach for doing type punning in
CUDA. See for example
- https://stackoverflow.com/questions/47037104/cuda-type-punning-memcpy-vs-ub-union
- https://developer.nvidia.com/blog/faster-parallel-reductions-kepler/
(the latter puns a double to an `int2`).
The issue is that for CUDA, the `memcpy` is not elided, and ends up
being an expensive operation.  We already have similar `reintepret_cast`s across
the Eigen codebase for GPU (as does TensorFlow).

there's no reason why we should follow the FSF's stupid recommendation for the naming of these files, right? This could give the wrong impression that Eigen is only GPL-licensed.
