    M llvm/test/Transforms/LowerMatrixIntrinsics/multiply-fused-dominance.ll

  Log Message:
  -----------
  [Matrix] Hoist address computation before multiply to enable fusion.

If the store address does not dominate the matrix multiply, try to hoist
address computation instructions without side-effects and/or memory
reads before the multiply, to allow fusion.
