#1604: fixnum arithmetic is ignored

Comment (by megane):
The scrutinizer cannot handle recursion. The type of `fib` is `*` inside
`fib`. This leads to the `+` being called with `*` arguments, so no
specialization can happen.
You can wrap the body of `fib` in `assume` with `fib` declared as `(fixnum
-> fixnum)`. I get `C_a_i_fixnum_plus` specializations with master this
way.
Maybe `fixnum-arithmetic` is still broken, though.
