Integrating CLs up to 15295. Descriptions of these CL's are included.
***
A couple changes to aeriel-vision for warp issue plot support
***
More arielvision changes to support the variable-entry length stacked bar chart
***
Properly printing the right resolution of dynamic warp ids
***.
Generalized the scheduler code and added detailed statistics for which warps issue each cycle.
Verified the execution of the LRR scheduler - still have to get the two level scheduler to work.
***
Implementing the 2lvl scehduler has it has been originally coded.
LRR on both the inner and outer levels
***
Adding in a debug tracing system to GPGPU-Sim.
I am sick of writing debug code - then having to comment out, ifdef out or delete it to checkin.
This also allows for print streams so the user can decided which traces they would like to see.
Every print in GPGPU-Sim should go through this system - then it will be really easy to only get the information you want and more importantly people will (a) write and (b) checkin code that actually profiles what they are building.
Reading tracefiles is superiour in many ways to single stepping since you can print the world and just vet the logfile for what you need.
This also fascilitates advice from the Debugging Rules! book which states that you should never throw away a debugging tool. Having debug prints that don't get thrown away is big.
***
Allowing the trace to be specified in the Make.
Run Make TRACE=0 to compile the code without any traces
***
Allowing prints from the performance sim to get the actual ptx instruction text
***
Getting the two level scheduler to actaully work...
What is released in fermi does not work at all - it effectively performs "static warp limit" from my CCWS paper.
Warps are never demoted from the active list since the functionality checking to see if they are waiting on a longop is completly broken.
Maybe if the original author had access to the tracing functions this would not have happened.
The islongop test was completely broken. It did not mark the register as used, it marked the register number in the instruction as used.
For example if this instruction was creating a long op:
ld r6 [r1]
It would mark register 0 as waiting for a long op (since it is register 0 of the two registers in this instruction), not register 6.
Additionally, whenever ANY instruction from a warp releases registers, ALL the longops being tracked for this warp get cleared....
The only way anyone ever thought this worked is if they did not test it....
***
Reworking the warp schedulers to share common code.
Making the GTX480 use gto by default. I am not sure wht they really use, but it really can't be LRR.
Also adding in a new file for custom shared trace defines. These are useful when you want a print that has some
additional criteria or information printed.
Verified that the schedulers all work to a first order based on traces.
***
Making it so you can run the stats collection scripts from any directory.
Also allow the caller to specify a stats file instead of just assume its always the same one

- Now there is only one macro for all use of unordered_map in the code.
- Moving all instances of gcc/cuda version detection into a single file.
- Adding a warning when the fallback is triggered.

makedepend generates the dependencies in Makefile.makedepend that is generated dynamically and cleaned with "make clean"
Next step is to use gcc's "-M" option and get rid of makedepend altogether.

the work of CL10697 which undone the changes to one file (stream_manager.cc). Here I undo the changes for 4 make files and more importantly the setup_enviroment file where I uncommented the include path of openCL as the case before CL10695, and I kept Tim changes to the CUDA path done later in CL10723 which he made originally to undo the work I did but didn't uncommet the openCL path which I do here.

for multiple configs of the built simulator to exist at one time. Now you no longer have to clean build when changing from debug to release configs it also eliminates the possibility of having a fraken-file where some objects are in debug and some are in release.

(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...)
