** fully decouple kernel compilation from kernel launch for opencl

changes required to do this (this enables oclReduction SDK 3.1 to pass
and is a prerequisite to Fermi style concurrent kernel launching)
- separate kernel launch for cuda and opencl (and init_grid functions)
- add pgm_info structure for holding kernel function_info pointer in
  _cl_program object after ptx compilation

** added support for clEnqueueNDRangeKernel with local_work_size==NULL
which is part of OpenCL spec and used in oclSortingNetworks (however, 
this is a braindead implementation that only handles the case where
global_work_size[0] is smaller than the max number of threads per
shader; moreover oclSortingNetworks is still not working but for what
looks like another reason)

** refactoring / cleanup
- g_global_symbol_table made static to ptx_parser.cc
- remove g_kernel_name_to_symtab_lookup (not really being used)
- moving various function prototypes into headers (e.g., if foo() defined
in bar.cc, then place prototype in bar.h)
- adding icnt_reg_options()
