0ef0eba580 * interp.c (hash): Update to be more accurate.
(lookup_hash): Call hash rather than computing the hash
        code here.
        (do_format_1_2): Handle format 1 and format 2 instructions.
        Get operands correctly and call the target function.
        (do_format_6): Get operands correctly and call the target
        function.
        (do_formats_9_10): Rough cut so shift ops will work.
        (sim_resume): Tweak to deal with format 1 and format 2
        handling in a single funtion.  Don't update the PC
        for format 3 insns.  Fix typos.
        * simops.c: Slightly reorganize.  Add condition code handling
        to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
        and "not" instructions.
        * v850_sim.h (reg_t): Registers are 32bits.
        (_state): The V850 has 32 general registers.  Add a 32bit
        psw and pc register too.  Add accessor macros
Fixing lots of stuff.  Starting to add condition code support.  Basically
check pointing the work to date.
