+ paramgr.pas: provide generic implementation of getintparaloc(). Once this method has been changed to use the procdef, it can reuse 'regular' parameter locations created by create_paraloc_info, so separate cpu-specific implementations of getintparaloc are no longer necessary. 
* parabase.pas: fixed tcgpara.getcopy, it should not modify the source object.
