When Use Kaby Lake-g(AMD Vega M GPU) to do the OpenGL CTS test, the case "
KHR-GL43.compute_shader.max" will fail. KHR-GL44.compute_shader.max and KHR-GL45.compute_shader.max also failed

Following is the environtment

Platform	KabyLake-G
CPU	Intel (R) Core (TM) i7-8809G CPU @3.10GHz
GPU	AMD(Radeon RX Vega M GH Graphics);

The test checks the value of GL_MAX_COMBINED_COMPUTE_UNIFORM_COMPONENTS using glGetInteger64v. The returned value is greater than 2G. The test incorrectly converts the value to GLint, which ends up being a negative number. This is a test bug.
