proposed patch (v2)

For both this and 401827, the problem was exposed by a gcc change to *not*
duplicate the result of some convert operation into 'undefined' portions of the
target register.  (And valgrind used/set the value in an undefined portion of
the result.  Adding printfs or playing with casts was enough to hide the
problem, so this took a bit to figure out. For this patch, i've updated the
valgrind emulation to fill in the proper (?) portion of the target registers. 
I have left the existing target register updates in place. 
This works in my sniff-tests, could still use validation in a cleanly built
environment.
