Re: [Aarch64] Add support for ARMv8.1 command line option

[Matthew Wahab <matthew dot wahab at arm dot com>]

Ping.

I've attached an updated patch and also added to the gas/NEW to mention the ARMv8.1 
support in the Aarch64 port. Updated change-log below.

Tested aarch64-none-linux-gnu with check-binutils and check-gas.

Ok for trunk?
