alpha.c (alpha_comparison_operator): Don't be so strict about DImode. 

* config/alpha/alpha.c (alpha_comparison_operator): Don't be
        so strict about DImode.
        (alpha_swapped_comparison_operator): Likewise.
        * config/alpha/alpha.md (*setne_internal): Name it.  Allow
        any integer output mode.
        (*setcc_internal): Likewise.
        (*setcc_swapped_internal): Likewise.
        (*movdicc_internal, *movdicc_lbc, *movdicc_lbs): Name them.
        (*mov[qhs]icc_internal): New.
