The main problem that half type is defined as _Float16 on the device and as manually implemented type on host so compiler could add _Float16 to the integration header and it will produce errors in host compilation. Signed-off-by: Mariya Podchishchaeva <mariya.podchishchaeva@intel.com>

What about using instead in 2019?

This test uses typedef in all places so I used it to save one style. I think changing all typedefs to usings not in scope of this PR :)

Because of the fact, that `half` type is not a standard C++ type and it is not supported everywhere, its implementation differs between host and device: C++ class with overloaded arithmetic operators is used on host and `_Float16` is used on device side. Previously, the switch between two version was implemented as preprocessor macro and having two different types caused some problems with integration header and unnamed lambda feature, see intel#185 and intel#960. This patch redesigned `half` implementation in a way, that single wrapper data type is used as `half` representation on both host and device sides; differentiation between actual host and device implementations is done under the hood of this wrapper.
