add OSFlags struct to AlphaISA/MipsISA namespace. The OS classes then use these OSFlags to access architecture-specific AND OS-specific

Browse source 
flags for their functions (e.g. OS::OSFlags::TG_MAP_ANONYMOUS)...

arch/alpha/tru64/process.cc:
sim/syscall_emul.hh:
    Add OSFlags to code
arch/mips/isa/decoder.isa:
    slight decoder changes (more stylistic then anything)
arch/mips/isa/formats/util.isa:
    spacing
arch/mips/isa_traits.hh:
    add OSFlags struct to MipsISA namespace. The OS classes then use these OSFlags to access architecture-specific and OS-specific
    flags for their functions
kern/linux/linux.hh:
    remove constant placement ... define OSFlags in linux.hh
kern/tru64/tru64.hh:
    define OSFlags in tru64
