......................................................................
stdlib: Allow se_binary_workload to setup LoopPoints
Added a set_se_looppoint_workload function to take in information for
workload and a stdlib LoopPoint object that stores all the information
the workload needed to run the LoopPoint sampling method.
Added a get_looppoint function to return the stdlib LoopPoint object.
