Thomas Preud'homme ced40572e4 [ARM] Add support for ARMv8-R in assembler and readelf 
=== Context ===

This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to add support for ARMv8-R in GAS:
instructions, build attributes and readelf.

=== Patch description ===

Although some differences exist for system registers, from GAS point of
view ARMv8-R supports the same instructions as ARMv8-A Aarch32 state
and a subset of its extensions. This patch therefore introduce a new
feature bit to distinguish the availability of the pan, ras and rdma
extensions between ARMv8-A and ARMv8-R and allow crypto, fp and simd
extensions to be used by ARMv8-R.

Most of the changes are then in the testsuite to (i) rename source files
and error output to be shared between ARMv8-A and ARMv8-R, (ii) rename
files with expected output for ARMv8-A build attributes and (iii) add
new files with expected output for ARMv8-R build attributes.
