Since we do source generation independently for each lane, if we use TL source for filtering, it becomes possible that lane 0's source happens to match lane 1/2/3's source even when they don't belong to the same warp. Since Vortex uses dcache req ID that is unique across instructions, using that for filtering prevents this bug. A better solution would be to do source generation for all lanes at a time though.
