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

d7f90b45b6 win: Fix incorrect thread suspend count due to ScopedProcessSuspend 
After https://codereview.chromium.org/1303173011/, the thread suspend
count would be one too large because the count is adjusted when the
process is suspended. Counteract this by passing in whether the
process is suspended or not so that the thread's suspension count
can be adjusted.

Add a test to sanity-check thread suspend count.
