[AArch64][PATCH 3/3] Add floating-point FP16 instructions

ARMv8.2 adds 16-bit floating point operations as an optional extension
to the ARMv8 FP support. This patch adds the new FP16 instructions,
making them available when the architecture extension +fp+fp16 is
specified.

The instructions added are:

- Comparisons and conditionals: FCMP, FCCMPE, FCMP, FCMPE and FCSEL.
- Arithmetic: FABS, FNEG, FSQRT, FMUL, FDIV, FADD, FSUB, FMADD, FMSUB,
  FNMADD and FNMSUB.
- Rounding: FRINTN, FRINTP, FRINTM, FRINTZ, FRINTA, FRINTX and FRINTI.
- Conversions: SCVTF (fixed-point), SCVTF (integer), UCVTF (fixed-point)
  UCVTF (integer), FCVTZS (fixed-point), FCVTZS (integer), FCVTZU
  (fixed-point), FCVTZU (integer), FCVTNS, FCVTNU, FCVTAS, FCVTAU,
  FCVTPS, FCVTPU, FCVTMS and  FCVTMU.
- Scalar FMOV: immediate, general and register
