Florian Hahn f605692d39 [LV] Remove unnecessary DoExtraAnalysis guard (silent bug) ...

canVectorize is only checking if the loop has a normalized pre-header if DoExtraAnalysis is true.
This doesn't make sense to me because reporting analysis information shouldn't alter legality
checks. This is probably the result of a last minute minor change before committing (?).
