[llvm] r286403 - Update vectorization debug info unittest.

New Revision: 286403

URL: http://llvm.org/viewvc/llvm-project?rev=286403&view=rev
Log:
Update vectorization debug info unittest.

Summary:
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.
