perf annotate: Support jump instruction with target as second operand

Architectures like PowerPC have jump instructions that includes a target
address as a second operand. For example, 'bne cr7,0xc0000000000f6154'.
Add support for such instruction in perf annotate.

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)

Corresponding perf annotate o/p:

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)
