[AArch64][PATCH 8/14] Support FP16 Adv.SIMD Across Lanes 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 Adv.SIMD Across Lanes, making them available
when +simd+fp16 is enabled.
The instructions added are: FMAXNMV, FMAXV, FMINNMV and FMINV.
The general form for these instructions is
<OP> <Hd>, <V>.<T>
where T is 4h or 8h.
The new instructions valid make uses of the 8H and 4H that were
previously illegal. The patch adjusts a test for illegal uses of vector
types to take this into account.
