Add quiesceNs, quiesceTime, quiesceCycles, and m5panic pseudo ops.

This changeset removes a check that prevents quiescing when an
interrupt is pending. *** You should only call quiesce if that
isn't a problem. ***

arch/alpha/isa/decoder.isa:
sim/pseudo_inst.cc:
sim/pseudo_inst.hh:
    Add quiesceNs, quiesceCycles, quisceTime and m5panic pseudo ops.
    These quiesce for a number of ns, cycles, report how long
    we were quiesced for, and panic the simulator respectively.
    The latter is added to the panic() function in the console and linux
    kernel instead of executing an infinite loop until someone notices.
cpu/exec_context.cc:
cpu/exec_context.hh:
    Add a quiesce end event to the execution contexted which upon
    executing wakes up a CPU for quiesceCycles/quiesceNs.
util/m5/Makefile:
    Make the makefile more reasonable
util/m5/m5.c:
    update the m5op executable to use the files from the linux tree
util/m5/m5op.S:
    update m5op.S from linux tree
util/m5/m5op.h:
    update m5op.h from linux tree
