// Two sets of macros:
// - TF_CALL_float, TF_CALL_double, etc. which call the given macro with
//   the type name as the only parameter - except on platforms for which
//   the type should not be included.
// - Macros to apply another macro to lists of supported types. These also call
//   into TF_CALL_float, TF_CALL_double, etc. so they filter by target platform
//   as well.
// If you change the lists of types, please also update the list in types.cc.
//
// See example uses of these macros in core/ops.
//
//
// Each of these TF_CALL_XXX_TYPES(m) macros invokes the macro "m" multiple
// times by passing each invocation a data type supported by TensorFlow.
//
// The different variations pass different subsets of the types.
// TF_CALL_ALL_TYPES(m) applied "m" to all types supported by TensorFlow.
// The set of types depends on the compilation platform.
//.
// This can be used to register a different template instantiation of
// an OpKernel for different signatures, e.g.:
