Scott Graham 4893a9b76d win: Capture some CRITICAL_SECTION debugging data
Capture the memory for the loader lock (can be inspected by !cs), as
well as all locks that were created with .DebugInfo which can be viewed
with !locks.

e.g.

0:000> !cs ntdll!LdrpLoaderLock
-----------------------------------------
Critical section   = 0x778d6410 (ntdll!LdrpLoaderLock+0x0)
DebugInfo          = 0x778d6b6c
NOT LOCKED
LockSemaphore      = 0x0
SpinCount          = 0x04000000

0:000> !locks -v
