* ghost.adb (Is_OK_Declaration): A reference to a Ghost entity may
appear within the class-wide precondition of a helper subprogram.
This context is treated as suitable because it was already
verified when we were analyzing the original class-wide
precondition.
Tested on x86_64-pc-linux-gnu, committed on master.
