Ignore MOD field for control/debug register move
This patch ignores the MOD field in control/debug register move instructions. gas/testsuite/ * gas/i386/cdr.d: New file. * gas/i386/cdr.s: Likewise. * gas/i386/x86-64-cdr.d: Likewise. * gas/i386/i386.exp: Run cdr and x86-64-cdr. opcodes/ * i386-dis.c (MOD_0F20): Removed. (MOD_0F21): Likewise. (MOD_0F22): Likewise. (MOD_0F23): Likewise. (dis386_twobyte): Replace MOD_0F20, MOD_0F21, MOD_0F22 and MOD_0F23 with "movZ". (mod_table): Remove MOD_0F20, MOD_0F21, MOD_0F22 and MOD_0F23. (OP_R): Check mod/rm byte and call OP_E_register.
