[PATCH][GAS][AArch64] Add new instructions for Armv8.4-a [Patch (4/6)]

[Nick Clifton]

Hi Tamar,

This patch does not work (in isolation).  I see errors like this:

  opcodes/aarch64-tbl.h:4202:81: error: 'QL_SHA512UPT' undeclared here (not in a function); did you mean 'QL_SHA256UPT'?
     SHA2_INSN ("sha512h",   0xce608000, 0xffe0fc00, cryptosha2, OP3 (Fd, Fn, Vm), QL_SHA512UPT, 0),
                                                                                 ^
  opcodes/aarch64-tbl.h:4204:77: error: 'QL_V2SAME2D' undeclared here (not in a function); did you mean 'QL_V2SAMESD'?

  etc..

I assume that this is because I need the earlier patches in the series applied.
So ... I am going to wait for the other patches to be checked in and then try
again.

Cheers
