Re: [PATCH] Re: change #9754: 5 x slowdown for perl -d

Based on my quick&dirty testing (the eventpos.pl and the input file xaa 
from the bug id #20218), on Tru64, with cc -O4, this claws us back almost
to the 5.6.1 speeds (execution speed 5.6.1 = 100, maint branch after this
patch = 117).  I'll do some further profiling to see where's the rest going.
(Unfortunately it seems that reverting the second-most-slowing-down
change #14920 that did cause a 40% drop (IIRC) back in between 5.7.2
and 5.7.3 doesn't give us back much, if any, of the speed.)
