executable bits

[Mike Stump]

In gcc/testsuite/g++.old-deja, the following files:

./g++.pt/t35a.C
./g++.pt/test4.C
./g++.robertl/eh990323-1.C
./g++.robertl/eh990323-2.C
./g++.robertl/eh990323-3.C
./g++.robertl/eh990323-4.C
./g++.robertl/eh990323-5.C
./g++.robertl/ice990323-1.C
./g++.robertl/ice990323-2.C
./g++.robertl/ice990323-3.C
./g++.robertl/ice990323-4.C
./g++.robertl/ice990323-5.C

need their x bits removed.
