PR69195, Reload confused by invalid reg_equiv
Optimizing indirect jumps to direct jumps, and deleting dead insns can
lead to changes in register lifetimes, which in turn can result in bad
reg_equiv info being passed to reload. So do these tasks before
calculating reg_equiv info.

* ira.c (recorded_label_ref): Delete.
(update_equiv_regs): Return void.
(indirect_jump_optimize): New function.
(ira): Call indirect_jump_optimize and delete_trivially_dead_insns
before regstat_compute_ri. Don't rebuild_jump_labels here.
Delete update_regstat.
