* opcodes/i386-dis.c (reg_table): Add XOP_8F_TABLE (XOP_09) to
reg_table[REG_8F][1]: for XOP instructions, ModRM.reg first points to
B.mm in the RXB.mmmmm byte, and so when B is set, we still should use
the xop_table.
(get_valid_dis386): Removed unused condition (from cut/n/paste) for
XOP instructions.
* gas/testsuite/gas/i386/x86-64-lwp.s: Updated to also contain
patterns with r[8-15] registers.
* gas/testsuite/gas/i386/x86-64-lwp.d: Same.
