More precise template parameter type for Platform::getInfo<>() about opencl-clhpp

[TSlivede]

The same applies to cl_device_info, cl_context_info, cl_event_info, cl_profiling_info, cl_mem_info, and so on.

Just search for template <cl_int name> in cl2.hpp. In all 18 occurrences, the template parameter type can be changed from cl_int to a more precise type. All those methods just forward name to another method as a (regular, non template) argument that has that more precise type.

This way it would be much more obvious what kind of values can be accepted as the template parameter.

This makes sense to me. @jprice, any idea why the these functions currently use cl_int as the template parameter? This issue affects both the old cl.hpp and the new cl2.hpp.

No, that history predates my involvement with this header. I can't think of any reason not to do this.
