df-problems.c (can_move_insns_across): Exit loop once we find a non-fixed, non-global register.

Browse Source 
* df-problems.c (can_move_insns_across): Exit loop once we
        find a non-fixed, non-global register.

        * ipa-pure-const.c (propagate_nothrow): Exit loop after
        setting can_throw.

        * omega.c (omega_eliminate_red): Break after setting red_found.
        (omega_problem_has_red_equations): Similarly after setting found.
        (omega_query_variable): Similarly after setting coupled.

        * trans-decl.c (gfc_build_dummy_array_decl): Exit loop after
        setting PACKED_PARTIAL.
