Antonio Sanchez db5691ff2b Fix some CUDA warnings. 
Added `EIGEN_HAS_STD_HASH` macro, checking for C++11 support and not
running on GPU.

`std::hash<float>` is not a device function, so cannot be used by
`std::hash<bfloat16>`.  Removed `EIGEN_DEVICE_FUNC` and only
define if `EIGEN_HAS_STD_HASH`. Same for `half`.

Added `EIGEN_CUDA_HAS_FP16_ARITHMETIC` to improve readability,
eliminate warnings about `EIGEN_CUDA_ARCH` not being defined.

Replaced a couple C-style casts with `reinterpret_cast` for aligned
loading of `half*` to `half2*`. This eliminates `-Wcast-align`
warnings in clang.  Although not ideal due to potential type aliasing,
this is how CUDA handles these conversions internally.
