[perl #129196] Crash/bad read with ‘evalbytes S’

5dc13276 added some code to toke.c that did not take into account
that the opnum (‘f’) argument to UNI* could be a negated op number.
PL_last_lop_op must never be negative, since it is used as an offset
into a struct.

Tests for the crash will come in the next commit.
