Add "k <= (x >> n) to (k << n) <= x" reduction to Word64Comparisons. This can help to reduce the below codes: 45: Int64Constant[164] 39: Load[kRepTaggedSigned|kTypeInt32](...) 40: BitcastTaggedToWordForTagAndSmiBits(39) 41: TruncateInt64ToInt32(40) 42: ChangeInt32ToInt64(41) 43: Word64Sar[ShiftOutZeros](42, 29) 46: Uint64LessThan(45, 43) into: 4530: Int32Constant[328] 39: Load[kRepTaggedSigned|kTypeInt32](...) 40: BitcastTaggedToWordForTagAndSmiBits(39) 41: TruncateInt64ToInt32(40) 46: Uint32LessThan(4530, 41) Change-Id: I6ca802c9bb3c941c689ebbcb4ae3072501555266 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3793464 Commit-Queue: Hao A Xu <hao.a.xu@intel.com> Reviewed-by: Nico Hartmann <nicohartmann@chromium.org> Cr-Commit-Position: refs/heads/main@{#82210}
