Fix rare segfaults and bugs with threads

There was a race in the "PL_ppaddr[OP_PADSV] save/restore dance" in that
perl might be compiling ops inside and outside the scope of the pragma at
the same time. We solve this by setting the op_ppaddr member of PADSV ops
to a_pp_deref during the peephole optimization phase.
