      Description

        Currently legVecZ operand is defined as follows:
        operand legVecZ() %{
          constraint(ALLOC_IN_RC(vectorz_reg_vl));
          match(VecZ);

          format %{ %}
          interface(REG_INTER);
        %}
        This allows legVecZ to be zmm0-zmm31 on platforms supporting AVX 512 vl.

        The legVecZ should instead be defined as:
        operand legVecZ() %{
          constraint(ALLOC_IN_RC(vectorz_reg_legacy));
          match(VecZ);

          format %{ %}
          interface(REG_INTER);
        %}
