After handling a break or continue statement while

executing a loop, reset the parser return code so
that we do not propagate the break/continue status
upward.

This problem was only visible under -O1, -O2, and
-O3, the defective code was not executed under -O0
or -O4.

This fixes Savannah bug #35884: Problem with break. 

This is the same fix as revision 23561, but for cint7
instead of cint5.
