     S4_stored_rl_at_vi
     S2_storew_rl_st_vi
     S4_stored_rl_st_vi

The release instructions are nop's in qemu.  The others behave as
  loads/stores.

The encodings for these instructions changed some "don't care" bits
     L2_loadw_locked
     L4_loadd_locked
     S2_storew_locked
     S4_stored_locked
