    x86_cse: Skip JUMP from asm goto

    Skip a single set of JUMP came from asm goto:

    (jump_insn 9 2 111 2 (parallel [
                (set (reg:SI 134)
                    (asm_operands/v:SI ("") ("=r") 0 []
                         []
                         [
                            (label_ref:DI 10)
                        ] x.c:6))
                (clobber (reg:CC 17 flags))
            ]) "x.c":6:3 -1
         (expr_list:REG_UNUSED (reg:CC 17 flags)
            (nil))
     -> 10)

    when checking the broadcast source.
