[TESTBUG] Fix the test failure of TestSelectFromTwoVectorOp.java on sve2 platforms

XMLWordPrintable

      According the AD file, partial cases where `vector_length_in_bytes > 8` of the vector API `selectFrom` are not supported on the AArch64 SVE2 platform.
      ```
            case Op_SelectFromTwoVector:
              // The "tbl" instruction for two vector table is supported only in Neon and SVE2. Return
              // false if vector length > 16B but supported SVE version < 2.
              // For vector length of 16B, generate SVE2 "tbl" instruction if SVE2 is supported, else
              // generate Neon "tbl" instruction to select from two vectors.
              // This operation is disabled for doubles and longs on machines with SVE < 2 and instead
              // the default VectorRearrange + VectorBlend is generated because the performance of the default
              // implementation was better than or equal to the implementation for SelectFromTwoVector.
              if (UseSVE < 2 && (type2aelembytes(bt) == 8 || length_in_bytes > 16)) {
                return false;
              }

              // Because the SVE2 "tbl" instruction is unpredicated and partial operations cannot be generated
              // using masks, we disable this operation on machines where length_in_bytes < MaxVectorSize
              // on that machine with the only exception of 8B vector length. This is because at the time of
              // writing this, there is no SVE2 machine available with length_in_bytes > 8 and
              // length_in_bytes < MaxVectorSize to test this operation on (for example - there isn't an
              // SVE2 machine available with MaxVectorSize = 32 to test a case with length_in_bytes = 16).
              if (UseSVE == 2 && length_in_bytes > 8 && length_in_bytes < MaxVectorSize) {
                return false;
              }
              break;
      ```
      But the test `TestSelectFromTwoVectorOp.java` didn't rule out these cases, leading to test failures on sve2 platforms where `MaxVectorSize > 16`.

      Error logs:
