* rtlanal.c (struct subreg_info, subreg_get_info, subreg_nregs):
New.
(subreg_regno_offset, subreg_offset_representable_p): Change to
wrappers about subreg_get_info.
(refers_to_regno_p, reg_overlap_mentioned_p): Use subreg_nregs.
* rtl.h (subreg_nregs): Declare.
* doc/tm.texi (HARD_REGNO_NREGS_HAS_PADDING): Update to refer to
subreg_get_info.
* caller-save.c (mark_set_regs, add_stored_regs): Use
subreg_nregs.
* df-scan.c (df_ref_record): Use subreg_nregs.
* flow.c (mark_set_1): Use subreg_nregs.
* postreload.c (move2add_note_store): Use subreg_nregs.
* reload.c (decompose, refers_to_regno_for_reload_p,
reg_overlap_mentioned_for_reload_p): Use subreg_nregs.
* resource.c (update_live_status, mark_referenced_resources,
