Previously it was storing a *pointer*, which left open the possibility of this pointer being null. We never made use of that possibility (it does not make sense), and most of the code was already assuming that. However, there were a couple of null-checks scattered around the code. This patch replaces the reference with a pointer, making the non-null-ness explicit, and removes the remaining null-checks. llvm-svn: 363381
