This changelist implements the following:

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.
