Hi Andrew,

I've committed this patch (obvious fix) to fix a bug in generic_register_byte().
You were using the 'regnum' instead of the loop index and this resulted in a wrong
byte position being computed. Ie:  reg_num * generic_register_size (reg_num).

It didn't show up for you because most targets use a fixed-size register definition (I guess).
For HC11, I have 2-byte reg as well as 1-byte reg, so it came up to invalid value, and
then aborted in frame_register().

	and not regnum when summing the size of all registers up to regnum.
