[patch] h8300.md: Don't use REGNO when its operand is notguaranteed to be a REG.


Hi,

Attached is a patch to tell h8300.md not to use REGNO when its operand
is not guaranteed to be a REG.

--enable-checking produced an internal compiler error, which led to
this patch.

Tested on h8300 port.  Committed.
