Alex Coplan 95830c988a aarch64: Add base support for Armv8-R 
This patch adds the basic infrastructure needed to support Armv8-R in
AArch64 binutils: new command-line flags, new feature bits, a new BFD
architecture, and support for differentiating between architecture
variants in the disassembler.

The new command-line options added by this patch are -march=armv8-r in
GAS and -m aarch64:armv8-r in objdump.

The disassembler support is necessary since Armv8-R AArch64 introduces a
system register (VSCTLR_EL2) which shares an encoding with a different
system register (TTBR0_EL2) in Armv8-A. This also allows us to use the
correct preferred disassembly for the new DFB alias introduced in
Armv8-R.
