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 Scalar Shift By Immediate to support
FP16, making this support available when +simd+fp16 is enabled.
The extended instructions are: SCVTF, FCVTZS, UCVTF and FCVTZU.
The general form for these instructions is
<OP> <Hd>, <Hs>, #<imm>
