* gencode.c: Fix various indention & style problems.

        Remove test code.  Remove #if 0 code.
        * interp.c: Provide prototypes for all static functions.
        Fix minor indention problems.
        (sim_open, sim_resume): Remove unused variables.
        (sim_read): Return type is "int".
        * simops.c: Remove unused variables.
        (divh): Make result of divide-by-zero zero.
        (setf): Initialize result to keep compiler quiet.
        (sar instructions): These just clear the overflow bit.
        * v850_sim.h: Provide prototypes for put_byte, put_half
        and put_word.
Cleaning up.
