[binutils-gdb/binutils-2_26-branch] [AArch64][PATCH 1/3] Support ARMv8.2 FP16 floating point instructions.;h=39be7778730799a3d505fb90b0a0e4e7fa0ab5a2

    [AArch64][PATCH 1/3] Support ARMv8.2 FP16 floating point instructions.
    ARMv8.2 adds 16-bit floating point operations as an optional extension
    to the ARMv8 FP support. This patch set adds support for the 16-bit FP
    instructions to binutils, enabling the instructions when both +fp and
    +fp16 architecture extensions are enabled.
    The patches in this series:
    - Add a feature macro for use by the encoding/decoding mechanism.
    - Adjust a utility function, used when disassembling, to support 16-bit
      floating point values.
    - Add the new scalar floating-point instructions.
    This patch adds the feature macro FP_F16 to the AArch64 encoding/decoding
    mechanism, enabling it when both +fp and +fp16 are selected.
