[AArch64][PATCH 3/14] Support ARMv8.2 FP16 Scalar Three Same instructions.
ARMv8.2 adds 16-bit floating point operations as an optional extension
to the floating point and Adv.SIMD support. This patch adds FP16
instructions to the group Scalar Three Register Same, making them
available when +simd+fp16 is enabled.
The instructions added are: FABD, FMULX, FCMEQ, FCMGE, FCMGT, FACGE,
FACGT, FRECPS and FRSQRTS.
The general form for these instructions is
<OP> <Hd>, <Hs>, <Hm>

* aarch64-asm-2.c: Regenerate.
* aarch64-dis-2.c: Regenerate.
* aarch64-opc-2.c: Regenerate.
* aarch64-tbl.h (aarch64_opcode_table): Add fp16 versions of
fmulx, fcmeq, frecps, frsqrts, fcmge, facge, fabd, fcmgt and
facgt to the scalar three same group.
