* simplify-rtx.c (simplify_relational_operation_1): Use CONST0_RTX
rather than const0_rtx in eq/ne-xor simplifications.

* reorg.c (relax_delay_slots): Move declaration of "trial_seq"
above the conditional, and convert the check on GET_CODE to a
dyn_cast, so that "trial_seq" is available as an rtx_sequence * in
the conditional. Simplify the conditional by using methods of
"trial_seq".
