  Log:
  MFC rev. 1.71, 1.72:
  
  Guess the number of arguments to a function somewhat better.
  Now GCC likes to stick a "mov %eax, %FOO" instruction before
  "addl $BAR, %esp" if the function just called returns an int,
  which is a very common case in the kernel.
  
  Return -1 from db_numargs() if number of args couldn't be guessed.
  Use this later to indicate in backtrace output that args shown are
  uncertain.
