Right now only non-SMT SE regression tests have been added back in. The rest are pending getting SMT working, and consolidating the FS configuration files.
Eventually support for different OSs can be added so you can specify which versions of the binary you want to run from one config file.
Note: mp-test1 doesn't have any reference stats because MP mode doesn't currently work. The test itself should probably work once the code is fixed.
SConstruct:
Updates to allow for regression tests to work via the command line "scons build/ALPHA_SE/test/debug/quick" and such once again.

First: Rename FullCPU and its variants in the o3 directory to O3CPU to differentiate from the old model, and also to specify it's an out of order model.

SConstruct:
Add in option USE_CHECKER to allow for not compiling in checker code. The checker is enabled through this option instead of through the CPU_MODELS list. However it's still necessary to treat the Checker like a CPU model, so it is appended onto the CPU_MODELS list if enabled.

Support for Python-called simulate() function:

to exit the simulation loop gracefully (instead of
calling exit() to terminate the process).

caller so it can be inspected for cause.

Move copyright notice back to C++ so we can print

Use PYTHONPATH environment var to set module path
(instead of clunky code injection method).
Move main control from here into Python:
- Separate initialization code and simulation loop
into separate functions callable from Python.
- Make Python interpreter invocation more pure (more
like directly invoking interpreter).
Add -i and -p flags (only options on binary itself;
other options processed by Python).
Import readline package when using interactive mode.

SimExitEvent is now SimLoopExitEvent, and uses
IsSimExit flag to terminate loop (instead of
