ARMv8.2-A adds 16-bit floating point versions of all existing VFP floating-point instructions. This is an optional extension, so all of these instructions require the FeatureFullFP16 subtarget feature. Most of these instructions are the same as the 32- and 64-bit versions, but with the type field (bits 23-22) set to 0b11. Previously the top bit of the size field was always 0, so the instruction classes only provided a 1-bit size field, which I have widened to 2 bits.
