* ira-build.c (form_loop_tree): Reverse BB walk.
(create_bb_allocnos): Likewise.
* ira-lives.c (make_regno_born_and_dead, regs_set): Delete.
(mark_reg_store): Rename to...
(mark_ref_live): ...this and take a df_ref argument instead of
note_stores arguments. Assert that we have a register.
(mark_reg_clobber): Delete.
(def_conflicts_with_inputs_p): New function.
(mark_reg_conflicts): Delete.
(mark_reg_death): Rename to...
(mark_ref_dead): ...this and take a df_ref argument instead of
a register. Assert that we have a register.
(process_bb_node_lives): Hoist frequency calculation out of
instruction walk. Convert from a forwards scan to a backwards scan.
Use DF_REF_USES and DF_REF_DEFS instead of register notes and
note_stores. Remove EH_RETURN_DATA_REGNO and regs_set handling.
(create_allocno_live_ranges): Don't create regs_set.
