Stream stats (#71)

* Temp commit for Justin and Cassie to sync on
code changes for adding per-stream status.

* Resolved compile errors.

* Removed redundant parameter

* Passed cuda_stream_id from accelsim to gpgpusim

* Cleaned up unused changes

* Changed vector to map, having operator problems.

* StreamID defaults to zero

* Implemented streams to inc_stats and so on

* Fixed TOTAL_ACCESS counts

* Implemented GLOBAL_TIMER.

* Fixed m_shader->get_kernel SEGFAULT issue in shader.cc.

* Use warp_init to track streamID instead of issue_warp

* Removed temp debug print

* Modified cache_stats to only print data from latest finished stream

Added optional arg to cache_stats::print_stats, cache_stats::print_fail_stats and their upstream functions. When streamID is specified, print stats
from that stream. When not specified, print all stats.

NOTE: current implementation depending on streamid never equals -1

* Removed default arg values of streamID

* modified constructor of mem_fetch to pass in streamID

* changed get_streamid to get_streamID

* Added TODO to gpgpusim_entrypoint.cc and power_stat.cc

* Only collect power stats when enabled

* print last finished stream in PTX mode using last_streamID

* take out additional printf

* Add a field to baseline cache to indicate cache level

* save gpu object in cache

* Print stream ID only once per kernel

* rm test print

* use -1 for default stream id

* cleanup debug prints

* remove GLOABL_TIMER

* Automated clang-format

* Should be correct to print everything in power model

* addressing concerns & errors

* Automated clang-format

* add m_stats_pw in operator+

* Automated Format
