Make more use of END_REGNO
An upcoming patch will convert hard_regno_nregs into an inline
function, which in turn allows hard_regno_nregs to be used as the
name of a targetm field. This patch rewrites uses that are more
easily (and efficiently) written as END_REGNO.

* config/frv/frv.c (FOR_EACH_REGNO): Use END_REGNO instead of
hard_regno_nregs.
* config/v850/v850.c (v850_reorg): Likewise.
* reload.c (refers_to_regno_for_reload_p): Likewise.
(find_equiv_reg): Likewise.
