Changes that get rid of the OSFlags and derive a new class of this format <architecture>-<OS>.

This class is derived from the original <OS> class and is used to define information that
is both architecure and OS specific (for example, the AlphaLinux class is derived from the
Linux class and defined in arch/alpha/linux/linux.hh).

SConscript:
    no need to compile linux.cc and tru64.cc now, since openFlagsTable has been moved
arch/alpha/SConscript:
    compile linux.cc and tru64.cc within alpha arch.
arch/alpha/linux/process.cc:
    template syscall functions on AlphaLinux instead of Linux ... AlphaLinux is derived off of Linux
arch/alpha/tru64/process.cc:
    template syscall functions on AlphaTru64 instead of Linux ... AlphaTru64 is derived off of Linux
    moved tableFunc syscall function into this file
arch/mips/SConscript:
    compile mips_linux.cc for openFlags table
arch/mips/isa_traits.hh:
    remove constants from here
arch/mips/linux_process.cc:
    template syscall functions on MipsLinux instead of Linux ... MipsLinux is derived off of Linux
kern/linux/linux.hh:
    remove OSFlags
kern/tru64/tru64.hh:
    remove OSFlags def., openFlagTable, and tableFunc ...
sim/syscall_emul.hh:
    go back to using "OS" instead of "OSFlags"
arch/alpha/linux/linux.cc:
    defines openFlagTable
arch/alpha/linux/linux.hh:
arch/alpha/tru64/tru64.hh:
    Alpha Linux constants placed here in class derived from Linux class
arch/alpha/tru64/tru64.cc:
    defines openFlagTable for AlphaTru64
arch/mips/mips_linux.cc:
    MIPS Linux open flag table
arch/mips/mips_linux.hh:
    Mips Linux constants placed here in class derived from Linux class
