ARMv8.1 is a set of optional architectural extensions to ARMv8. Support for the
individual extensions, added by other patches, is enabled by adding the
extension name to the "armv8-a" architecture name. This patch supports using
"armv8.1-a" as an architecture name in its own right, making it the same as
"armv8-a" with all ARMv8.1 extensions enabled.
This patch depends on the ARMv8.1 patches submitted earlier:
- PAN extension: https://sourceware.org/ml/binutils/2015-05/msg00182.html
- Limited ordering regions:
https://sourceware.org/ml/binutils/2015-05/msg00187.html
- ARMv8.1 Adv.SIMD: https://sourceware.org/ml/binutils/2015-05/msg00189.html
Tested with check-gcc and check-binutils for aarch64-none-linux-gnu.
Ok for trunk?

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?
