Calculate Job Wheel Jobs

#   ROUTINE: CALCULATE JOB WHEEL JOBS
#   Determines which jobs are visible on the job wheel for the current unit?
#       Parameters:
#           r4 = (formationScreenUnitIndex) ? (Sometimes *0x8018ba20): Formation screen unit index. (Not party unit index; can be different for guests)
#           r5 = (p2) ? (Sometimes 0x801c83f8)
#           r6 = (p3) ? (Sometimes 2)
#       Returns:
#           r2 = How many jobs are visible on the job wheel for the current unit? (Saved to *0x801c83f0 in routine 0x8011a378 (0x8011a3b0) when opening Change Job screen)
