These two patches implement the base support of builtin_zero_pattern into match.pd. To implement the other part requires match-and-simplify inside phiopt to support moving 2 statements from the middle-bb. The match.pd part is already incldued. I will try to get to it next week.
Also __builtin_clrsb has not been moved yet either and I will get to that next week as well.
