Currently, in most cases the compiler generates a func value symbol when it is referenced, except when building a shared object it generates the func value symbol when the function is declared. The comment says this was necessary because we cannot deduplicate DUPOK symbols across DSO boundaries. But the dynamic linker is just fine to resolve symbols with the same name across DSO boundaries. Another problem may be that the address of the PLT stub may be used. When such a func value is deferred, when the runtime needs to scan its arguments, it cannot look up the PC to find the function and therefore cannot find its stack map. This is not a problem now as deferred functions always have no arguments. Remove the special case for shared linkage.
