re PR rtl-optimization/38711 (ira should not be using df-lr except at -O1.)
PR rtl-optimization/38711
* df.h (df_get_live_out, df_get_live_in): Make static inline functions.
* df-problems.c (df_get_live_out, df_get_live_in): Moved to df.h.
* ira-lives.c (process_bb_node_lives): Use df_get_live_out instead of
DF_LR_OUT.
* ira-build.c (create_bb_allocnos): Likewise.
(create_loop_allocnos): Likewise, and use df_get_live_in instead of
DF_LR_IN.
* ira-emit.c (generate_edge_moves): Likewise.
(add_ranges_and_copies): Likewise.
* ira-color.c (ira_loop_edge_freq): Use df_get_live_out instead of
DF_LR_OUT, and df_get_live_in instead of DF_LR_IN.
* ira.c (mark_elimination): Update DF_LR and DF_LIVE.
(build_insn_chain): Use df_get_live_out instead of DF_LR_OUT.
(do_reload): Remove the DF_LIVE problem for -O1.
