[AArch64][PATCH 6/14] Support FP16 Vector Indexed Element 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 Vector Indexed Element, making them available
when +simd+fp16 is enabled.
The instructions added are: FMLA, FMLS, FMUL and FMULX.
The general form for these instructions is
<OP> <V>.<T>, <V>.<T>, <V>.h[<idx>]
where T is 4h or 8h
