Nikita Popov 2fab927546 [LoopVectorize] Convert some tests to opaque pointers (NFC) 
Check lines for some of these tests were regenerated. The difference
is that with opaque pointers SCEVExpander always emits i8 GEPs,
making the address calculation explicit. This is a known problem
that will be solved long term by making all address calculations
explicit.
