Current test cases are checking if the loop can be vectorized, if a loop can be vectorized then the number of interations is known. While it would be better to check the loop's number of iterations directly. This patch updates the test cases accordingly. Bootstrap and regtest pass on ppc,ppc64le and x86_64. Is this ok for trunk?
