    [PR118560][LRA]: Fix typo in checking secondary memory mode for the reg
class

      The patch for PR118067 wrongly checked hard reg set subset.  It worked
for
    the equal sets as in PR118067.  But it was wrong in other cases as in
    PR118560 (inordinate compile time).

    gcc/ChangeLog:

            PR target/118560
            * lra-constraints.cc (invalid_mode_reg_p): Exchange args in
            hard_reg_set_subset_p call.
