[AArch64][PATCH 1/14] Support ARMv8.2 FP16 Adv.SIMD instructions.

ARMv8.2 adds 16-bit floating point operations as an optional extension
to floating point and Adv.SIMD support. This patch set adds the 16-bit
Adv.SIMD vector and scalar instructions to binutils, making them
available when both +simd and +fp16 architecture extensions are enabled.
The series also adds support for a new vector type, 2H, used by the FP16
scalar pairwise instructions.

The patches in this series:
- Add a FP16 Adv.SIMD feature macro for use by the encoding/decoding
  routines.
- Add FP16 instructions in the group Vector Three Register Same.
- Add FP16 instructions in the group Scalar Three Register Same.
- Add FP16 instructions in the group Vector Two Register Misc.
- Add FP16 instructions in the group Scalar Two Register Misc.
- Add FP16 instructions in the group Vector Indexed Element.
- Add FP16 instructions in the group Scalar Indexed Element.
- Add FP16 instructions in the group Adv.SIMD Across Lanes.
- Add FP16 instructions in the group Adv.SIMD Modified Immediate.
- Rework some code for handling vector types to weaken its assumptions
  about available vector-types.
- Add support for the 2H vector type.
- Add FP16 instructions in the group Adv.SIMD Scalar Pairwise.
- Add FP16 instructions in the group Adv.SIMD Shift By Immediate.
- Add a FP16 instructions in the group Adv.SIMD Scalar Shift By
  Immediate.

This patch adds the feature macro SIMD_F16 to the AArch64
encoding/decoding routines. It is used to decide when the new
instructions are available to the assembler and is true when both +simd
and +fp16 are selected.
