[AArch64][PATCH 1/2] Add support for ARMv8.2 DC CVAP instruction.

Browse Source 
ARMv8.2 adds the new system instruction DC CVAP. This patch series adds
support for this instruction to binutils, enabled when -march=armv8.2-a
is selected.

The AArch64 binutils record of some system registers uses a boolean
value to hold the single flag currently supported for them. To allow
these registers to be limited to specific architectures, the first patch
in this series replaces the boolean flag with a bitset and feature test.
