[PATCH] D83329: [PGO][PGSO] Add profile guided size optimization to loop vectorization legality.

Reproduced https://crbug.com/1106813.

The problem was that we were querying the profile of the newly created loop, as opposed to the original loop in InnerLoopVectorizer.

Querying against the original loop (and saving it in the constructor before the transformations because the profile of the original loop could change as it is used as the fallback loop) should fix the issue.
