    middle-end: check that both sides of complex expression is a mul.

    Both sides of the VEC_PERM_EXPR need to be a MULT but the check
    was accidentally checking if both sides are a mul.

    The FMS case would be handled by the validate_multiplication but
    this makes the requirement more explicit and we exit earlier.
