[PATCH] config/bfin/bfin.c (hwloop_optimize): Set JUMP_LABEL() after emit jump_insn

[Chen Gang]

JUMP_LABLE() must be defined after optimization completed. In this case,
it is doing optimization, and is almost finished, so it is no chances to
set JUMP_LABLE() next. The related issue is Bug 65803.

        * config/bfin/bfin.c (hwloop_optimize): Set JUMP_LABEL() after
        emit jump_insn.
