Anna Thomas cce7c24af1 NFC: Add a test to LV showing that reduction is not possible when reduction var is reset in the loop
Added a test case to reduction showing where it's illegal to identify
vectorize a loop.
Resetting the reduction var during loop iterations disallows us from
widening the dependency cycle to VF, thereby making it illegal to
vectorize the loop.
