Immature profiles report "-1" as a call site count and callers have to handle it as a special case.
If `ciCallProfile::count()` is used as is, it breaks call site frequency computation (makes the result negative) and, hence, negatively affects inlining decisions.

The code below demonstrates the issue:
 
    private static final int SIZE = 1_000_000;

    @Benchmark
    public MyList<Point> erasedIndirect() {
        var result = ListMinMap.<Point>createIndirectErased(SIZE);
        for (int i = 0; i < SIZE; i++) {
            result.set(i, erased.get(i).times(23));
        }
        return result;
    }

    static <T> MyList<T> createIndirectErased(int size) {
        return ErasedList.create(size);
    }
