        * cp1.c: Fix more comment spelling and formatting.
        (value_fcr, store_fcr): Use fenr_FS rather than hard-coding value.
        (denorm_mode): New function.
        (fpu_unary, fpu_binary): Round results after operation, collect
        status from rounding operations, and update the FCSR.
        (convert): Collect status from integer conversions and rounding
        operations, and update the FCSR.  Adjust NaN values that result
        from conversions.  Convert to use sim_io_eprintf rather than
        fprintf, and remove some debugging code.
        * cp1.h (fenr_FS): New define.
