Compiler_System_Version to be False.
* opt.ads: Add new flag Opt.Address_Is_Private
* targparm.ads, targparm.adb: Set new flag Opt.Address_Is_Private
Add new parameter Compiler_System_Version to avoid checking for
completeness of parameters when compiler is compiling itself.
Allows old versions of GNAT to be compiled with new compiler.
