[PATCH 03/11] x86emul: handle AVX512-FP16 Map5 arithmetic insns

This encoding space is a very sparse clone of the "twobyte" one. Re-use that table, as the entries corresponding to invalid opcodes in Map5 are simply benign with simd_size forced to other than simd_none (preventing undue memory reads in SrcMem handling early in x86_emulate()). Signed-off-by: Jan
