succesfully but there are some minor quirks to iron out. Who would've known a DELAY SLOT introduces that much complexity?! arrgh!
Anyways, a lot of this stuff had to do with my project at MIPS and me needing to know how I was going to get this working for the MIPS
ISA. So I figured I would try to touch it up and throw it in here (I hate to introduce non-completely working components... )

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.
src/cpu/SConscript:
Keep a list of SMT supporting CPUs so that the regression tests can easily specify which CPUs to use if they are SMT only.
