Add macro for checking if some flags are set This way we don't need to repeat the argument twice. I didn't replace all instances. I think it's better to leave out: - asserts - comparisons like x & y == x, which are mathematically equivalent, but here we aren't checking if flags are set, but if the argument fits in the flags. 2018-04-20 13:36:20 +00:00			`@@`
