	* config/tc-a29k.c (md_begin): When opcodes are mashed together in
	the table, require that the one without bit 0x1000000 set come
	first.  Require further that it be case 'b' or 'P'.  The a29k
	opcode table already meets these constraints.
	(machine_ip): When handling case 'i' or 'A', make sure that the
	appropriate opcode really exists by looking at the next entry in
	the opcode table.
