x86: Print {bad} on invalid broadcast in OP_E_memory
Don't print broadcast for scalar_mode, and print {bad} for invalid broadcast. gas/ PR binutils/28381 * testsuite/gas/i386/bad-bcast.s: Add a new testcase. * testsuite/gas/i386/bad-bcast.d: Likewise. * testsuite/gas/i386/bad-bcast-intel.d: New. opcodes/ PR binutils/28381 * i386-dis.c (static struct): Add no_broadcast. (OP_E_memory): Mark invalid broadcast with no_broadcast=1 and Print "{bad}"for it. (intel_operand_size): mark invalid broadcast with no_broadcast=1. (OP_XMM): Mark scalar_mode with no_broadcast=1.
