    M llvm/test/Transforms/LoopVectorize/runtime-checks-difference.ll

  Log Message:
  -----------
  [LV]  Add another test for incorrect runtime check generation.

Add a variation of @nested_loop_outer_iv_addrec_invariant_in_inner with
the dependence sink and source swapped to extend test coverage.

Also simplifies the test by removing an unneeded reduction.

  Log Message:
  -----------
  [LAA] Require AddRecs to be in the innermost loop for diff-checks.

The simpler diff-checks require pointers with add-recs from the same
innermost loop, but this property wasn't check completely. Add the
missing check to ensure both addrecs are in the innermost loop.

Fixes #57315.
