* config/tc-xtensa.c (xtensa_move_labels): Remove loops_ok argument. 

Do not check is_loop_target flag.
	(xtensa_frob_label): Adjust calls to xtensa_move_labels.
	(xg_assemble_vliw_tokens): Likewise.  Also avoid calling
	xtensa_move_labels for alignment of loop opcodes.

/* The "loops_ok" argument is provided to allow ignoring labels that
define loop ends. This fixes a bug where the NOPs to align a
loop opcode were included in a previous zero-cost loop:
loop a0, loopend
<loop1 body>
loopend:
loop a2, loopend2
<loop2 body>
would become:
loop a0, loopend
<loop1 body>
nop.n <===== bad!
loopend:
loop a2, loopend2
<loop2 body>
This argument is used to prevent moving the NOP to before the
loop-end label, which is what you want in this special case. */
