This PR introduces the support of integer BufferLoadNodes in `arith::IntervalSetEvaluator` as well as a unittest. Prior to this PR, the evaluator always return `IntervalSet::Everything()` (that is `[-∞, +∞]`) once it encounters a BufferLoad. However, as long as 1) the buffer data _is of type integer_ and 2) the indices of the BufferLoad _contain no variable_ that needs to be relaxed during evaluation, we can keep the BufferLoad as it is. Besides, we're considering introducing `assume_in_range` for buffers for the use of range/region analysis. With `assume_in_range`, even when the indices of BufferLoad contain some variables to be relaxed, we can just return the asserted range, which is more compact, instead of the universe. cc @yzh119 @Hzfengsy @spectrometerHBH @junrushao1994 -- This is an automated message from the Apache Git Service.
