+/// End-to-end test for computing matrix-multiplication using linalg.mmt4d. In
+/// particular, demonstrates how the following MLIR sequence (implemented in
+/// @matmul_via_mmt4d):
+///
+///   A_pack = linalg.pack A
+///   B_pack = linalg.pack B
+///   C_pack = linalg.pack C
+///   out_pack = linalg.mmt4d(A_pack, B_pack, C_pack)
