Keren Zhou 307b5caa49 [BACKEND] Fix scan issues on repetitive warps and improve perf when there's a single warp on the axis (#2330)
1. On the axis, using `getAxisNumWarpsWithUniqueData` instead of getting
the raw number of warps to avoid communication among warps that handle
the same piece of data.
2. When there's a single warp on the axis, using warp Intrinsics for
communication and skip shared memory.

Need a follow up PR for code clean up.
