CLOVER_CL_VERSION_OVERRIDE allows overriding default OpenCL version
supported by Clover, analogous to MESA_GL_VERSION_OVERRIDE for OpenGL.
CLOVER_CL_C_VERSION_OVERRIDE allows overridng default OpenCL C version.

+<h3>Clover state tracker environment variables</h3>

+<ul>
+<li>CLOVER_CL_VERSION_OVERRIDE - allows overriding OpenCL version returned by
+ clGetPlatformInfo(CL_PLATFORM_VERSION) and
+ clGetDeviceInfo(CL_DEVICE_VERSION). Note that the setting sets the version
+ of the platform and all the devices to the same value.
+<li>CLOVER_CL_C_VERSION_OVERRIDE - allows overriding OpenCL C version reported
+ by clGetDeviceInfo(CL_DEVICE_OPENCL_C_VERSION) and the value of the
+ __OPENCL_VERSION__ macro in the OpenCL compiler.

<h3>Softpipe driver environment variables</h3>
<ul>
<li>SOFTPIPE_DUMP_FS - if set, the softpipe driver will print fragment shaders
