state_tracker: Fix bug in conditional discards with native ints.

A bool is 0 or ~0, and KILL_IF takes a float arg that's <0 for discard or
>= 0 for not.  By negating it, we ended up doing a floating point subtract
of (0 - ~0), which ended up as an inf.  To make this actually work, we
need to convert the bool to a float.
