Description
In globalDefinitions_xlc.hpp there is a redefinition of NULL to work around an issue with one of the AIX headers (<dirent.h>).  Once all uses of NULL in HotSpot have been replaced with nullptr, there is no longer any need for this, and it can be removed.

Seems we have the same/similar e.g. in src/hotspot/share/utilities/globalDefinitions_visCPP.hpp // NULL vs NULL_WORD: // On Linux NULL is defined as a special type '__null'. Assigning __null to // integer variable will cause gcc warning. Use NULL_WORD in places where a // pointer is stored as integer value. #define NULL_WORD NULL
