An alias can suppress method redefinition warning

Fix memory leak at the same named alias [Bug #18516]
When aliasing a method to the same name method, set a separate bit
flag on that method definition, instead of the reference count
increment. Although this kind of alias has no actual effect at
runtime, is used as the hack to suppress the method re-definition
warning.
