Detect inline cycles faster

E.g. in the following code

    fun x() {}
    inline fun f() { x(); g() }
    inline fun g() { x(); f() }

the old implementation of inline cycle detection bailed out after
generating 3 calls of x() in each function, while the new one stops
after 2. In other words, code generation for a single function is no
longer reentered.
