[PATCH v7 4/6] perf annotate: Support jump instruction with target as second operand

Current perf is not able to parse jump instruction when second operand
contains target address. Arch like powerpc has such instructions. For
example, 'bne  cr7,0xc0000000000f6154'.

objdump o/p:
  c0000000000f6140:   ld     r9,1032(r31)
  c0000000000f6144:   cmpdi  cr7,r9,0
  c0000000000f6148:   bne    cr7,0xc0000000000f6154
  c0000000000f614c:   ld     r9,2312(r30)
  c0000000000f6150:   std    r9,1032(r31)
  c0000000000f6154:   ld     r9,88(r31)

Before patch:
         ld     r9,1032(r31)
         cmpdi  cr7,r9,0
      v  bne    3ffffffffff09f2c
         ld     r9,2312(r30)
         std    r9,1032(r31)
  74:    ld     r9,88(r31)

After patch:
         ld     r9,1032(r31)
         cmpdi  cr7,r9,0
      v  bne    74
         ld     r9,2312(r30)
         std    r9,1032(r31)
  74:    ld     r9,88(r31)
