[PATCH] D152278: [SCEV] Compute SCEV for ashr(add(shl(x, n), c), m) instr triplet

Hey @nikic @mkazantsev can you please review this patch, I stumbled upon this while working on a bug in LSR, this patch does fail one of the unit test-case in LSR. I believe that might be an effect of SCEV of this AShr pattern being computed, as LSR generally does do some optimizations based on the Shl + Add + AShr instructions.
