RISC-V: Misaligned memory access with COH

      We have different base_offset (4 bytes instead of 8 bytes) with COH. This causes misaligned memory accesses for several instrinsics like String.Compare.
      The reason is that we process 8 bytes starting at the first array element for each iteration in the main loop. As a result, we have performance regressions
      on platform with slow misaligned memory accesses like Unmatched and Premier P550 SBCs.
