注意
* k1, ..., k7 は新しいopmaskレジスタです。
* z, sae, rn-sae, rd-sae, ru-sae, rz-saeの代わりにT_z, T_sae, T_rn_sae, T_rd_sae, T_ru_sae, T_rz_saeを使ってください。
* `k4 | k3`と`k3 | k4`は意味が異なります。
* {1toX}の代わりにptr_bを使ってください。Xは自動的に決まります。
* 一部の命令はメモリサイズを指定するためにxword/yword/zword(_b)を使ってください。
+* setDefaultEncoding()でencoding省略時のEVEX/VEXを設定できます。
