[Beignet] [PATCH 00/19] Add half float support.

[junyan.he at inbox.com]

From: Junyan He <junyan.he at linux.intel.com>

Add the half float support for BDW later platform.
Some accurate problems need to verify, for example, when the value
of sin(x) is close to pi/2, the difference is about 15% to float
version.
The builtin functions for geometric and convert_rtp _rtn _rtz _rte
is absent, will be added later.
