I'm not sure - can I use CHECK-NOT(s) for a multi-line pattern?

A bit thinking: semantically I want `not (LINE_PATTERN_1 and LINE_PATTERN_2 and LINE_PATTERN3)`, which means I may do something roughly like `(not LINE_PATTERN_1) or (not LINE_PATTERN_2) or (not LINE_PATTERN_3)`, `not LINE_PATTERNx` can be expressed as CHECK-NOT, but I'm not sure if we have a way to express `or`.
