[Mesa-dev] [PATCH] clover: Return 0 as storage size for local kernel args that are not set

[Tom Stellard]

The storage size for local kernel args can be queried before the
arguments are set by using the CL_KERNEL_LOCAL_MEM_SIZE param
of clGetKernelWorkGroupInfo().

The spec says that if local kernel arguments have not been specified,
then we should assume their size is 0.
