After newobject, we don't need to write zeroes to initialize the object. It has already been zeroed by the allocator. This is already handled in most cases, but because we run builtin decomposition after the opt pass, we don't handle cases where the zero of a compound builtin is being written. Improve the zero detector to handle those cases.
