[Bug tree-optimization/32500] [4.2 Regression] Loop optimization limits range to size of array used inside loop

[ed at fxq dot nl]

Sorry if I'm being a nitpick...

The committed testcase contains a small error; it has an off-by-one bug that
causes a small buffer overflow.

The line:

      foo(numbers[i]);

should be replaced with:

      foo(numbers[i - 1]);

It shouldn't cause any real problems, because it's just a testcase, but maybe
some quite intelligent new optimizer might trip on that.
