[test] Fix widen-iv.ll under NPM

Browse Source 
The -loop-flatten legacy pass preserves loop analyses. The legacy PM
will check all passes that preserve loop analyses that they preserve
LCSSA. This implicitly involves running -loop-simplify. The test
shouldn't depend on verify flags being set in order to run
-loop-simplify, so explicitly add it. The new PM ends up not running it
otherwise.
