[PATCH] D87140: [GlobalISel] Avoid making G_PTR_ADD with nullptr

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

This is probably wrong for non integral pointers. Why not do this as a combine later? We need to start recognizing G_PTRADD (constant) + constant anyway to handle lowered LDS addresses
