Armv8.2-A adds FP16 support, i.e. f16 is not only a storage-only type, but it also supports performing data processing on 16-bit floating-point quantities. All the necessary (tablegen) groundwork of adding the ARMv8.2-A FP16 (scalar) instructions was done in D15014. To take advantage of this, this patch avoids promotion of f16 to f32 types when the subtarget supports FullFP16, which enables instruction selection of these FP16 instructions.
