[AArch64] Expand llvm.histogram intrinsic to support umax, umin, and uadd.sat operations (#138447) This patch extends the llvm.histogram intrinsic to support additional update operations beyond the existing add. Specifically, the new supported operations are: * umax: unsigned maximum * umin: unsigned minimum * uadd.sat: unsigned saturated addition Based on the discussion from: https://discourse.llvm.org/t/rfc-expanding-the-experimental-histogram-intrinsic/84673
