// Function: createScheduleInstructionsWithSSAPass(..)
// 
// Purpose:
//   Entry point for instruction scheduling on SSA form.
//   Schedules the machine instructions generated by instruction selection.
//   Assumes that register allocation has not been done, i.e., operands
//   are still in SSA form.
