In the course of working with the ia16 port, I found a case of subreg

which easily could be, with the attached change.

* rtlanal.c (subreg_get_info): set info->nregs from hard_regno_nregs.
I really think we need a testcase for this. Or at least a very clear
description of the situation. ie, what is xregno, xmode & ymode.
It's probably also useful to indicate what hard_regno_nregs is for the
given xregno and ymode.
