[RFA] Update D10V target to use new Harvardized type casts.

[Michael Snyder <msnyder@cygnus.com>]

This one-line change lets the D10V back-end recognize the new
Harvardized type casts eg. "(@code int *)", so that a pointer 
can be forced into the address space of choice.

The exact same change can be used for (most) other Harvard back-ends.

2001-11-14  Michael Snyder  <msnyder@redhat.com>

	* d10v-tdep.c (d10v_pointer_to_address): Use new type flag
	TYPE_FLAG_CODE_SPACE to recognize a pointer that has been cast
	into the instruction address space.
