(processor_target_table): Use PROCESSOR_POWER6 for power6. Add power6x. Add MASK_MFPGPR for power6x. (POWERPC_MASKS): Add MASK_MFPGPR. (rs6000_override_options): Set rs6000_always_hint to false for power6. Set rs6000_align_branch_targets. Replace rs6000_sched_groups check with rs6000_align_branch_targets. Use PROCESSOR_POWER6. (last_scheduled_insn): New variable. (load_store_pendulum): New variable. (rs6000_variable_issue): Set last_scheduled_insn and cached_can_issue_more. (rs6000_adjust_cost): Add power6 cost adjustments. (rs6000_adjust_priority): Replace is_dispatch_slot_restricted with insn_must_be_first_in_group. Add power6 priority adjustments.
