freedreno/ir3: fix indirects tracking

cp would update instr->address but not update the indirects array
resulting in sched getting confused when it had to 'spill' the address
register.  Add an ir3_instr_set_address() helper to set instr->address
and also update ir->indirects, and update all places that were writing
instr->address to use helper instead.
