Beignet 0.8.0 (2014-02-12)
Beignet version 0.8.0 has been released. As there are many key features
accomplishment and bug fixes included in this version, we decide to jump
the version to 0.8.0 from 0.3.0. The highlighted improvements are as below:
 * Implemented all mandatory features required by OpenCL spec 1.1,
   including the long data type support, half data type support,
   profiling support etc.
 * Improved most of the builtin math functions' precisions.
 * Implemented register spill along with the linear scan register allocation
 * Support llvm builtin functions: llvm.memset and llvm.memcpy.
 * Fixed the broken the data liveness analysis algorithm.
 * Fixed the barrier hang issue.
 * Work around some sampler/image hardware restrication and make the image
   function fully comply with the spec.
 * Beignet 0.8.0 could get nearly 100% pass rate with piglit ocl test suite,
   and about 99% pass rate with the OpenCV's ocl test suite on Intel HD4000
