perf annotate browser: Bandaid offsets/jump label objdump ambiguity

We need to cope with things like:

$ objdump  -d --no-show-raw -S -C /lib/modules/3.4.0-rc2+/build/vmlinux
<SNIP>
ffffffff8125ec60 <copy_user_generic_unrolled>:
 * Output:
 * eax uncopied bytes or 0 if successful.
 */
ENTRY(copy_user_generic_unrolled)
	CFI_STARTPROC
	cmpl $8,%edx
ffffffff8125ec60:	cmp    $0x8,%edx
	jb 20f		/* less then 8 bytes, go to byte copy loop */
ffffffff8125ec63:	jb     ffffffff8125ecf5 <copy_user_generic_unrolled+0x95>
	ALIGN_DESTINATION
<SNIP>
ffffffff8125ec8d:	je     ffffffff8125ecd9 <copy_user_generic_unrolled+0x79>
1:	movq (%rsi),%r8
ffffffff8125ec8f:	mov    (%rsi),%r8
2:	movq 1*8(%rsi),%r9
ffffffff8125ec92:	mov    0x8(%rsi),%r9
3:	movq 2*8(%rsi),%r10
ffffffff8125ec96:	mov    0x10(%rsi),%r10
4:	movq 3*8(%rsi),%r11

<SNIP>

Probably expect that the length of the addr field be the same...

Lazy move for now, back to supporting suppressing the address on callq lines...
