gprofng: include a new function in the right place

Static function name is not available in stripped libraries.
In this case, gprofng maps PC to a fake function like <static>@0xPC (<libname>).
Sometimes gprofng creates two functions instead of one.
Also FUNC_FLAG_SIMULATED is needed for these fake functions.
