Gian-Carlo Pascutto 7424532859 Ensure clGetKernelWorkGroupInfo return value fits. 
In LocalMemUsage(), there's a first call to clGetKernelWorkGroupInfo
to get the "bytes" amount needed to store the result from
CL_KERNEL_LOCAL_MEM_SIZE. However, the actual value passed is an
"auto result = size_t", which in 32-bit mode is 4 bytes, regardless
of the previous return value. The spec describes that it will actually
be a cl_ulong which is 8 bytes. To prevent stack corruption, make sure
we are in fact passing a cl_ulong.

Also adjust all callers to take the changed type into account.
