This enables `NULL` pointer dereference checking in the compiler. This isn’t as good as static analysis, but it should hopefully catch some simple errors without too high a false positive rate. If the false positive rate is too high to be useful, we can always disable it again. Signed-off-by: Philip Withnall <pwithnall@gnome.org> Helps: #1767
