Work around nvcc 9.0 compiler bug for open-source Tensorflow build.

With the current implementation, when I (unintentionally and transitively)
include absl/types/optional.h in a CUDA compilation unit, I get the following
nvcc error message:
  INFO: From Compiling tensorflow/core/kernels/crop_and_resize_op_gpu.cu.cc:
  external/com_google_absl/absl/types/optional.h: In member function 'void absl::optional_internal::optional_data_dtor_base<T, <anonymous> >::destruct()':
  external/com_google_absl/absl/types/optional.h:185:50: error: '__T0' was not declared in this scope
         data_.~T();

I've also seen similar compilation failures online, for flat_hash_map:
https://devtalk.nvidia.com/default/topic/1042599/nvcc-preprocessor-bug-causes-compilation-failure/

The bug is always around unnamed template parameters. Therefore, the workaround is to make them named.

Add parens around calls to std::numeric_limits<>::min and
