[PATCH] Check number of iterations for test cases pr101145

[Jiufu Guo via Gcc-patches]

PR101145 is supporting if the number of iterations can be calculated
for the 'until wrap' condition.  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?

BR,
Jiufu
