When no explicit loop is marked to be vectorized and VPlan native path is
enabled. The innermost loop will be vectorized using the inner loop vectorizer.
Previously this setup caused errors like this to happen:

This patch fixes that and add a test case to test inner loop vectorization
happens when VPlan native path is enabled.
