* interp.c (sim_size): Now allocates unified memory for imap segments
	0,1,2, and 127. Initializes imap0 and imap1 to 0x1000.  Initializes dmap to 0.
	(sim_write): Just call xfer_mem().
	(sim_read): Just call xfer_mem().
	(xfer_mem): New function. Does appropriate memory mapping and copies bytes.
	(dmem_addr): New function. Reads dmap register and translates data
 	addresses to local addresses.
	(pc_addr): New function. Reads imap register and computes local address
	corresponding to contents of the PC.
	(sim_resume): Change to use pc_addr().
	(sim_create_inferior): Change reinitialization code. Also reinitializes
	imap[01] and dmap.
	(sim_fetch_register): Add fake registers 32,33,34 for imap0, imap1, and dmap.
	(sim_store_register): Add fake registers 32,33,34 for imap0, imap1, and dmap.

	* simops.c (MEMPTR): Redefine to use dmem_addr().
	(OP_5F00): Replace references to STate.imem with dmem_addr().

	* d10v-sim.h (State): Remove mem_min and mem_max. Add umem[128].
	(RB,SW,RW,SLW,RLW): Redefine to use dmem_addr().
	(IMAP0,IMAP1,DMAP,SET_IMAP,SET_IMAP1,SET_DMAP): Define.
