Put regression tests back into m5. They are located in the "tests" directory. The directory output and reference outputs have changed slightly. Now the directory is ALPHA_SE/test/<test>/<cpu_model>/, and for the reference stats <test>/ref/<arch>/<cpu_model>
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.

For now using the checkpoint or switchcpu pseudo instructions will return control to Python, returning the cause to be the instruction name. The user's script must then interpret the reason for exiting the simulation loop and handle the action accordingly. This may change in the future.
src/sim/pseudo_inst.cc:
Exit sim loop with a specific string to indicate to Python what caused the exit. The user's script needs to interpret the exit events and handle them as desired.

Checker ignores any faults that occur in syscall emulation mode for now.
src/cpu/checker/cpu_impl.hh:
The only fault we handle in SE causes troubles when invoked with the Checker. This is because it changes state within the process, and not the checker, so the state isn't correct when the main CPU calls invoke. It's safe to just ignore the fault in the Checker and continue.
