        * frontend-passes.c (enum matrix_case):  Add case A2B2T for
        MATMUL(A,TRANSPoSE(B)) where A and B are rank 2.
        (inline_limit_check):  Also add A2B2T.
        (matmul_lhs_realloc):  Handle A2B2T.
        (check_conjg_variable):  Rename to
        (check_conjg_transpose_variable):  and also count TRANSPOSE.
        (inline_matmul_assign):  Handle A2B2T.
