Scott Graham 5a21de6a1b win: Retrieve thread context for x64
Retrieve context and save to thread context. NtQueryInformationThread
is no longer required (right now?) because to retrieve the CONTEXT, the
thread needs to be Suspend/ResumeThread'd anyway, and the return value
of SuspendThread is the previous SuspendCount.

I haven't handle the x86 case yet -- that would ideally be via
Wow64GetThreadContext (I think) but unfortunately that's Vista+, so I'll
likely need to to a bit of fiddling to get that sorted out. (It's actually
likely going to be NtQueryInformationThread again, but one thing at a
time for now.)
