Currently every time we encounter an indirect call of a known function, we try to evaluate the inline cost of that function. In case of a recursion, that evaluation never stops.

The solution I propose is to evaluate only the indirect call of the function, while any further indirect calls (of a known function) will be treated just as direct function calls, which, actually, never tries to evaluate the call.

Fix PR35469.
