By itself, this commit doesn't really change anything. It lays the
groundwork for using the cpu state in follow up commits, both for
engine state and for cpu state. Splitting things up this way so it
is easier to see how things have changed.
This removes the last uses of PARAMS from sim.

* sh/interp.c: Don't use PARAMS.
* v850/sim-main.h: Don't use PARAMS.
* v850/v850_sim.h: Don't use PARAMS.
* d10v-sim.h (simops): Add flag is_long.
(State): Add pc_changed. Instructions which update the PC should
use the JMP macro which sets this.
(JMP): New macro. Sets the PC and the pc_changed flag.
* gencode.c (write_opcodes): Add is_long field.
* interp.c (lookup_hash): If we blindly apply a short opcode's mask
to a long opcode we could get a false match. Check the opcode size.
(hash): Add a size field to the hash table.
(sim_open): Initialize size field in hash table.
(sim_resume): Change to logic for setting the PC. Used to increment the
PC if it had not been changed. This didn't allow single-instruction loops.
Now checks the flag State.pc_changed. Also now stops when ^C is received.
(dmem_addr): Fix translation of data segments to unified memory.
(sim_ctrl_c): New function. When ^C is received, set stop_simulator flag.
* simops.c: Changed all branch and jump instructions to use new JMP macro.
(OP_20000000): Corrected trace information to show this is a ldi.l, not
a ldi.s instruction.
