Add the ability to track stats in user defined sets of function calls. code can be generated via the base/instrum_codegen.pl script to easily change the functions being tracked. the only thing the user needs to do is add code in tru64System to change how the callerMap is populated.

command line:

m5.* <config file> <args> --server.system:bin=true to track function calls in the server
m5.* <config file> <args> --client.system:bin=true to track function calls in the client

base/statistics.cc:
    make an adjustment to the way stats are printed for FS_MEASURE
base/statistics.hh:
    add a name() virtual function to GenBin.  add a debug printf for activate().
    add amake MainBin the default bin when FS_MEASURE.
cpu/exec_context.cc:
    initialize swCtx to null upon creation of an xc
cpu/exec_context.hh:
    add a SWContext pointer to every execution context.
cpu/simple_cpu/simple_cpu.cc:
    process calls and returns for FS_MEASURE
cpu/simple_cpu/simple_cpu.hh:
    add this so idleCycles will not be accessed before all stats are constructed
kern/tru64/tru64_events.cc:
    add a FnEvent that fires whenever a function we're tracking is called.  implement the process() virtual function for it.
kern/tru64/tru64_events.hh:
    add FnEvent
kern/tru64/tru64_system.cc:
    send bin parameter to System constructor.  add bin parameter to Tru64System object.  initialize all the FnEvent and MainBin members of Tru64system.  also, populate the calling map that indicates whether a function call is on the path we're tracking.
kern/tru64/tru64_system.hh:
    modify the Tru64System class to support FS_MEASURE
sim/system.cc:
    add a bin parameter to System class.  initialize a MainBin to hold the stats for nonPath.
sim/system.hh:
    add a map of to match bins to function names.  add a swCtx map to map pcb addresses to SWContext *s.  Add some supporting functions.
