While I'm waiting for legion to run make m5 compile with a few more compilers

SConstruct:
src/SConscript:
    Add flags for Intel CC while i'm at it
src/base/compiler.hh:
    the _Pragma stuff needst to be called this way unless someone happens to have a cleaner way
src/base/cprintf_formats.hh:
    add std:: where appropriate
src/base/statistics.hh:
    use this->map since icc was getting confused about std::map vs the locally defined map
src/cpu/static_inst.hh:
    Add some more dummy returns where needed
src/mem/packet.hh:
    add more dummy returns where needed
src/sim/host.hh:
    use limits to come up with max tick
