    x86/emul: Add structure names to opcode tables
    
    No functional change, but it makes the diff context line more helpful when
    reviewing patches which alter the opcode tables.  e.g. Consider:
    
      --- a/xen/arch/x86/x86_emulate/x86_emulate.c
      +++ b/xen/arch/x86/x86_emulate/x86_emulate.c
      @@ -370,7 +370,7 @@ static const struct {
           [0x0c ... 0x0f] = { .simd_size = simd_packed_fp },
           [0x10] = { .simd_size = simd_packed_int },
           [0x13] = { .simd_size = simd_other, .two_op = 1 },
      -    [0x14 ... 0x15] = { .simd_size = simd_packed_fp },

    which is entirely ambiguous between 0f38 and 0f3a, and the same diff with 
this
