Pin instruction storage

The operands in each instruction needs to be pinned because if
auto-compaction runs in iseq_set_sequence, then the objects could exist
on the generated_iseq buffer, which would not be reference updated which
can lead to T_MOVED (and subsequently T_NONE) objects on the iseq.
