Remove a bunch of function pointers in the output stage; they are never changed and don't add any value. Also make "ofile" a global variable and let the backend use it directly. All we ever did with these variables were stashing it in locals and using them as-is anyway for no benefit. Also change the global error function, nasm_error() into a true function which invokes a function pointer internally. That lets us use direct calls to it. Signed-off-by: H.
