Test case showing incorrect offset handling in xcb_sync_systemcounter_name

I just hit this again today, and extracted the attached test case to prove it,
then found this bug when searching before filing a new one.

When compiled with either -m32 or -m64, it outputs (run against Xorg post-1.12
git master):

4c: VICEIDLETIME 7 (resolution: 4)
  Actual name: DEVICEIDLETIME 7
4b: VICEIDLETIME 6 (resolution: 4)
  Actual name: DEVICEIDLETIME 6
4a: VICEIDLETIME 5�� (resolution: 4)
  Actual name: DEVICEIDLETIME 5
49: VICEIDLETIME 4 (resolution: 4)
  Actual name: DEVICEIDLETIME 4
48: VICEIDLETIME 3 (resolution: 4)
  Actual name: DEVICEIDLETIME 3
47: VICEIDLETIME 2 (resolution: 4)
  Actual name: DEVICEIDLETIME 2
3f: LETIME  (resolution: 4)
  Actual name: IDLETIME
3e: RVERTIMEh (resolution: 4)
  Actual name: SERVERTIME
sizeof(xcb_sync_systemcounter_t) = 16
