[AArch64][PATCH 13/14] Support FP16 Adv.SIMD Shift By Immediate instructions.
ARMv8.2 adds 16-bit floating point operations as an optional extension
to the floating point and Adv.SIMD support. This patch extends
instructions in the group Adv.SIMD Shift By Immediate to support FP16,
making this support available when +simd+fp16 is enabled.
The new instructions legal make some uses of the 4h vector type that had
been invalid. This patch adjusts a test that checks for these uses.
The extended instructions are: SCVTF, FCVTZS, UCVTF and FCVTZU.
The general form for these instructions is
<OP> <Vd>.<T>, <Vs>.<T>, #<imm>
where T is 4h or 8h.
