Updated tests
================
Comment at: llvm/test/CodeGen/AArch64/i128-cmp.ll:24
; CHECK-NEXT: eor x9, x0, x2
; CHECK-NEXT: orr x8, x9, x8
; CHECK-NEXT: cmp x8, #0
----------------
Also checking if it's possible to use setcccarry to lower setcc eq/ne. It seems like it may improve code on x86, ARM and AArch64, but I'd prefer fixing it separately.
Support SETCCCARRY lowering to SBCS instruction.
