[turbofan] Perform element index computation in word64 on 64-bit platforms. This allows us to fuse the address computation with the actual memory access operation on x64, which reduces the register pressure and the number of instructions. There's probably some follow up cleanup that has to happen to make sure the machine operator optimizations that are relevant to word64 computations are also available (similar to what is already available for word32).
