[PATCH] D26428: Update vectorization debug info unittest.

[Dehao Chen via llvm-commits]

danielcdh created this revision.
danielcdh added a reviewer: probinson.
danielcdh added a subscriber: llvm-commits.

The change will test the change in r286159.
The idea behind the change: Make the dbg location different between loop header and preheader/exit. Originally, dbg location 21 exists in 3 BBs: preheader, header, critical edge (exit). Update the debug location of inside the loop header from !21 to !22 so that it will reflect the correct location.
