Adjust testcase for O2 vectorization[Wuninitialized]
It looks like it's just the the location of the warning that's off,
the warning itself is still issued but it's swallowed by the
dg-prune-output directive.
Since the test was added to verify the fix for an ICE without
vectorization I think disabling vectorization should be fine.
Ideally, we would understand why the location is wrong so let's keep
this bug open and add a comment to the test referencing this bug.
gcc/testsuite/ChangeLog:
* g++.dg/warn/Wuninitialized-13.C: Add -fno-tree-vectorize.
