In the Intel HD 4000 driver a shader has to be deleted in the same context in which it is created. However, because you can't use a rendering context on different threads, to maintain the multithreaded compilation, the solution was to use the `GL_ARB_get_program_binary` and copy the binary generated for the shader and generate a shader on the main context using that binary. This solution is limited only to Intel HD 4000 and windows. Reviewers: fclem Reviewed By: fclem Differential Revision: https://developer.blender.org/D5019
