Merge vectorIntrinsics with default: aarch64

[Viswanathan, Sandhya]

Hi Yang,

I did a manual merge of vectorIntrinsics branch with default branch today after about 4 months.
Could you please take a look at assembler_aarch64.hpp? The lines to be corrected are commented with // VERIFY MERGE:

  INSN(maxv,   0, 0b011001, false); // VERIFY MERGE
  INSN(minv,   0, 0b011011, false); // VERIFY MERGE
  INSN(cmeq,   1, 0b100011, false); // VERIFY MERGE
  INSN(cmgt,   0, 0b001101, false); // VERIFY MERGE
  INSN(cmge,   0, 0b001111, false); // VERIFY MERGE


  INSN(smaxv,  0, 0b110000101010, 0); // VERIFY MERGE
  INSN(sminv,  0, 0b110001101010, 0); // VERIFY MERGE

Best Regards,
Sandhya
