[PATCH] D26869: [LV] Add flag for ignoring target info

This patch adds a flag ("loop-vectorize-ignore-target-info") that causes the vectorizer to use the default TTI implementation instead of one based on the target. This is useful for ensuring consistent results across targets when testing. The run lines of all target-independent tests have been updated to use the flag.
