Add an additional base argument to Assembler::AddScaled so it now computes: dest <- base + (index << scale) + offset If base is kNoRegister (or ZR when available), then it emits instructions optimized for computing: dest <- (index << scale) + offset (i.e., its previous implementation) Add AddScaled to AssemblerBase to ensure the same interface across all architectures. Rework the backend of CalculateElementAddress to use AddScaled appropriately, which unifies it across architectures.
