Moved where some alpha specific source files were mentioned to be in the alpha specific Sconscript, and took advantage of the os specific directories for the process files.

Browse source 
arch/sparc/faults.cc:
    Remove fake fault, fix to have normal m5 line length limit, and change pointers to be const pointers so that the default faults aren't changed accidentally.
arch/sparc/faults.hh:
    Fix to have normal m5 line length limit, change pointers to const pointers.
arch/sparc/faults.hh:
    Added a typedef for the Addr type, and changed the formatting of the faults slightly.
arch/sparc/faults.hh:
    ur
    Using cleaned up fault class deiffinitions
arch/sparc/faults.hh:
    Added typedef for Addr
arch/sparc/faults.hh:
    Made Addr a global type
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Changed Fault * to Fault, which is a typedef to FaultBase *, which is the old Fault class renamed.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Changed Fault to be a RefCountingPtr
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    MachineCheckFaults and AlignmentFaults are now generated by the ISA, rather than being created directly.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Put the Alpha faults into the AlphaISA namespace
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Moved the _stat for MachineCheckFault and AlignmentFault into the isa specific classes to prevent instantiation of the generic classes.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Changed ev5_trap from a function of the execution context to a function of the fault. The actual function still resides in the execution context.
arch/sparc/faults.cc:
    AlphaFault is now an abstract class.
arch/sparc/faults.hh:
    AlphaFault is now an abstract class. Also, AlphaMachineCheckFault and AlphaAlignmentFault multiply inherit from both AlphaFault and from MachineCheckFault and AlignmentFault respectively. These classes get their name from the generic classes.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    moved ev5_trap fully into the fault class.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Changed the name of the fault's invocation method from ev5_trap to invoke.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Moved the fault invocation code into the fault class fully, and got rid of the need for isA.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Got rid of the multiple inheritance in the Fault classes, and the base MachineCheck and Alignment faults.
arch/sparc/faults.cc:
    bk cp ../alpha/faults.cc faults.cc
arch/sparc/faults.hh:
    bk cp ../alpha/faults.hh faults.hh
SConscript:
    Moved the alpha specific source files into the alpha specific SConscript
arch/alpha/SConscript:
    Moved the alpha specific source files into the alpha specific SConscript, and moved the process files into the new os specific subfolders.
arch/alpha/linux/process.cc:
arch/alpha/process.hh:
arch/sparc/process.hh:
arch/alpha/tru64/process.cc:
    Changed the include paths to use the new os specific directories.
