perf annotate: Allow whitespace between insn operands

Browse Source 
The llvm-objdump adds a space between the operands while GNU objdump
does not.  Allow a space to handle the both.

In GNU objdump:

  Disassembly of section .text:                                      here
                                                                      |
  ffffffff81000000 <_stext>:                                          v
  ffffffff81000000:	48 8d 25 51 1f 40 01 	lea    0x1401f51(%rip),%rsp
  ffffffff81000007:	e8 d4 00 00 00       	call   ffffffff810000e0 <verify_cpu>
  ffffffff8100000c:	48 8d 3d ed ff ff ff 	lea    -0x13(%rip),%rdi

In llvm-objdump:

  Disassembly of section .text:                                      here
                                                                       |
