* rtlanal.c (struct subreg_info, subreg_get_info, subreg_nregs):
New.

(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
