changes to parse instructions. Carry functionality NOT fully implemented; .cc instructions function like their unmodified ueqivelents. Also modified GTX750Ti config to model L1 data cache as simply not being used for global loads (instead of not existing at all). Changed ptxinfo parsing to avoid crashing when info includes texture information.

L1 Cache and Shared Memory configurations across kernels. The support
enable the user to specify two more configurations (Preferred L1) or
(Preferred Shared Memory) besides the default config. If the
cudaFuncSetCacheConfig API is used to set the cache configuration
of a specific kernel to either of these configuration (cudaFuncCachePreferShared,
cudaFuncCachePreferL1), the simulator will change the cache configuration
at kernel launch accordingly, if there is no alternative configurations
provided to the simulator it will use the default configurations with a
warning message display

bug 18 (external) for detail. The blocked SDK benchmarks are still not working due to mismatch of texture element layout in memory between real GPU and GPGPU-Sim.

- Updated PTX parser to support CUDA 4.1 and 4.2.
- Revised fatbin workaround to a more robust version (with comments explaining it).
- Added print_simulation_time() in gpgpu_sim_thread_concurrent().

There is a problem with the linkage on my machine. Before this changelist the code didn't build on my machine. After it it builds but fails to run due to missing dynamic linkage. And obviously it breaks the jenkins build.

1. Adds support for using cuobjdump for both ptx and ptxplus execution. This has been tested with CUDA 4.0
. Ptxplus is no longer supported through decuda/decuda_to_ptxplus
2. Adds support for converting the SASS output by cuobjdump to ptxplus. This has been tested with CUDA 4.0
. The old path that extracts ptx from cubin files is still preserved
3. Adds a bank group model. (WARNING: memory config has changed, please adapt yours). To disable the bank groups model, set nbkgrp to 1 and tCCDL and tRTPL to 0
Diff the configuration files to learn about how to use those new options.

Parameters are finalized at kernel launch, which means the contents
of parameter memory are initialized. Kernel arguement names have a
fixed order, hence same address should be assigned on subsequent
kernel launches of same kernel in other streams provided the data size
param_t::size of arguments for each kernel launch is identical (an
assertion has been added to check this is true).

OpenCL)
This changelist adds full support for streams supported by a new class,
stream_manager and enables concurrent execution of kernels from different
streams.
- fast_regression.sh fails for simpleMultiCopy, simpleStreams (other tests
passing)
** Known issues **
- Kernel parameter passing is not done correctly for concurrent kernel execution
(somehow concurrentKernels is not affected by this): the parameters are
stored inside function_info, which is shared among parallel kernel launches
so that the values passed into the launch are likely to get overwritten if
multiple grids are launched in parallel streams.
- Statistics are printed out whenever the simulation thread runs out of
cuda commands (doesn't make sense to print out when a kernel ends during
concurrent kernel execution). This will probably require further tweaking
so as to be more compatible with data collection scripts.

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.
