2. some bug fixes for warp_inst_t
3. creating a new class, gpgpu_t, which contains the functional "memory" state visible
to all threads running on a GPU (doing this as part of my continuing effort to hunt
down and eradicate every global variable that is not the top level "the gpu")
4. other misc. changes
Almost passing CUDA 3.1 regression? oclHistogram keeps failing under torque, but
does not fail when run on the command line from the same directory.

refactoring: create warp_inst_t that provides notion of a group of scalar instructions
traveling down the pipeline.
delete DWF
delete MIMD
delete warp_tracker
delete old writeback stage, replace it with a stub that just writes back everything
delete old pipeline model
current status: MSHR's need to change to deal with the new structure

cache)
2. update gpgpusim.config for Quadro to use L1 cache geometry from Henry's ISPASS paper
3. minor edit to CUDA api : add notion of fat_cubin_handle (currently not used for anything)
4. minor edits to deadlock detection message (more accurate reporting of source of deadlock)
5. other minor edits

(i'll use "fermi" for more disruptive changes to the pipeline model such
as updating the MSHRs and getting rid of the warp tracker, ripping out DWF, etc...)

this integrates the ptxplus functional model changes, but has only been
verified with CUDA 3.1 PTX regressions (which pass)
still need to verify ptxplus itself is working in this branch

(add scoreboard logic from ptxplus branch and modified operand collector
with parallel ALU/SFU pipelines)

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()
