Make O3CPU model independent of the ISA

Browse Source 
Use O3CPU when building instead of AlphaO3CPU.

I could use some better python magic in the cpu_models.py file!

AUTHORS:
    add middle initial
SConstruct:
    change from AlphaO3CPU to O3CPU
src/cpu/SConscript:
    edits to build O3CPU instead of AlphaO3CPU
src/cpu/cpu_models.py:
    change substitution template to use proper CPU EXEC CONTEXT For O3CPU Model...

    Actually, some Python expertise could be used here. The 'env' variable is not
    passed to this file, so I had to parse through the ARGV to find the ISA...
